Treatment of varicoceles in childhood and adolescence with Tauber's antegrade scrotal sclerotherapy

PURPOSE: The aim of this study was to evaluate surgical complications and the outcome of grade II and III varicoceles treated with Tauber's antegrade scrotal sclerotherapy. METHODS: A total of 21 patients with a median age of 13 (range, 10 to 21) years and left-sided grade II and III varicoceles were treated with Tauber's antegrade scrotal sclerotherapy and underwent follow-up over a median period of 23 months (range, 9 to 35). RESULTS: One grade II varicocele persisted after antegrade sclerotherapy for 6 months. After a second sclerotherapy 6 months later, no further recurrence was detected. One patient with a grade II to III varicocele had a grade I varicocele recurrence 14 months after operation. Three patients showed a slight hydrocele postoperatively. CONCLUSION: This limited series indicates that Tauber's antegrade scrotal sclerotherapy is a safe and effective treatment for grade II and III varicoceles in children and adolescents.     

Laparoscopic treatment of pediatric varicocele: a multicenter study of the italian society of video surgery in infancy

PURPOSE: We report preliminary results of a multicenter study of the Italian Society of Video Surgery in Infancy on the laparoscopic treatment of pediatric varicocele. MATERIALS AND METHODS: A total of 161 children 6 to 16 years old (median age 12.5) underwent laparoscopic treatment of varicocele at 6 pediatric surgery divisions. Varicocele was on the left side in 159 cases (98.7%) and bilateral in 2 (1.3%). Two boys had recurrent left varicocele. All children were treated with laparoscopy, including ligation of the spermatic veins only in 28 (17.3%), and ligation of the testicular veins and artery in 133 (82.7%). In 10 boys (6.2%) an additional procedure was done simultaneously, including closure of an apparently patent peritoneal vaginal duct on the right side in 7 and resection of epiploic adhesions between the intestinal loops and abdominal wall from previous appendectomy in the remaining 3. RESULTS: Average operative time was 30 minutes and hospitalization was about 24 hours. At followup there were 13 minor complications (8%), including left hydrocele in 9 children who underwent the Palomo technique, minor scrotal emphysema in 2 and umbilical granuloma in 2. In our series varicocele recurred in 1 boy (3.5%) who underwent ligation of the spermatic veins only and in 3 (2.2%) treated with the Palomo technique. CONCLUSIONS: Our preliminary experience shows that the results of the laparoscopic approach are comparable to those of the open approach. However, the important advantages of laparoscopy over the open approach are its minimal invasiveness and precision of intervention. Moreover, laparoscopy allows treatment of other intra-abdominal pathological conditions using the same anesthesia, as in 10 patients in our series. We believe that ligating the testicular veins and artery is preferable to ligating the testicular veins only, even if the incidence of hydrocele is not negligible after the Palomo procedure.     

The role of Doppler ultrasonography in determining the proper surgical approach to the management of varicocele in children and adolescents

In a study from Italy, colour-Doppler ultrasonography was a reliable diagnostic tool in the preoperative assessment of patients with varicocele. The authors also found that it helped to distinguish those who could be treated laparoscopically from those who should be treated by microsurgical subinguinal ligature. OBJECTIVE: To investigate whether colour Doppler ultrasonography (CDUS) is a reliable diagnostic tool for selecting patients with varicocele to undergo either laparoscopy or open microsurgical subinguinal ligation. PATIENTS AND METHODS: In a 3-year period, 42 boys affected by left varicocele were evaluated before surgery by inguinal and scrotal CDUS. Using this method it was possible to distinguish Coolsaet type-1 varicocele (due to isolated renal-internal spermatic vein reflux) and Coolsaet type-3 varicocele (due to associated renal-internal spermatic reflux and iliac-deferential reflux). Boys with Coolsaet type-1 varicocele were treated by a laparoscopic transperitoneal Palomo procedure, whereas those with Coolsaet type-3 varicoceles were treated by lymphatic-sparing microsurgical subinguinal ligation. RESULTS: The varicocele was Coolsaet type-3 in six patients (14%), who had microsurgical open surgery, and the remaining 36 (86%) had Coolsaet type-1 and had laparoscopic surgery. At the follow-up there was no venous scrotal reflux. In two patients in the laparoscopic group a hydrocele developed after surgery, which resolved spontaneously. CONCLUSIONS: This study showed that CDUS was a reliable diagnostic tool for assessing boys with varicocele. It clearly distinguished Coolsaet-type 1 varicoceles that can be treated laparoscopically, from Coolsaet type-3 varicoceles that should be treated with microsurgical subinguinal ligature.     

Laparoscopic varicocele ligation in children and adolescents using isosulphan blue: a prospective randomized trial

OBJECTIVES: To evaluate, in a randomized prospective trial in children and adolescents, the feasibility of isosulphan blue-based lymphatic vessel preservation during laparoscopic varicocelectomy and its impact on the complication rate, as the operative management of varicoceles remains controversial. PATIENTS AND METHODS: In all, 50 consecutive patients were randomly assigned to two laparoscopic varicocelectomy groups. The indications for surgery included scrotal pain and a difference in testicular size, as well as severe cosmetic impairment. All the patients had a laparoscopic varicocelectomy using three ports. Patients in group A had standard laparoscopy, while those in group B had additional isosulphan blue administered. After surgery, the patients were assessed at 3, 6 and 12 months for varicocele recurrence, hydrocele formation, atrophy, pain or other complications. RESULTS: There were no intraoperative complications or conversions to open surgery. There were no adverse reactions, scrotal haematomas or atrophy. At 3 months after surgery, the incidence of hydrocele in group A was 20% whereas in group B no hydroceles were detected (P = 0.025); at 6 months the 20% still had hydroceles. One patient in each group had varicocele recurrence associated with persistent pain. In two patients in group B, blue pigmentation of the left hemiscrotum persisted at the 3-month follow-up but resolved by 6 months. CONCLUSIONS: Laparoscopic repair of varicoceles using isosulphan blue helps to identify and preserve the lymphatic drainage. It prevents secondary hydrocele formation, the most common complication, with no supplementary risk to the patient. Also, testicular oedema causing impaired spermatogenesis can be avoided.

Laparoscopic varicocelectomy with preservation of the testicular artery in adolescents

PURPOSE: The aim of this study was to determine if laparoscopic varicocelectomy (LV) with preservation of the testicular artery (TA) is a satisfactory alternative to standard open surgical techniques in adolescents. METHODS: Between June 1993 and June 1999 left LV was performed on 40 boys, median age, 12 years (range, 9 to 16 years). Selection for surgical correction included size of the varicocele, symptoms, and clinical or ultrasound assessment for testicular hypotrophy. Eight patients had undergone previous left-sided inguinal surgery, 5 of these for varicocele. Three laparoscopic ports were used. The TA was identified and preserved with the aid of a Doppler flow transducer ("Smart Needle"). All the testicular veins were ligated and divided. The inferior epigastric (IE) veins also were ligated in 19 patients. The operating time was a mean of 1 hour. The postoperative follow-up for a median of 19.5 months (range, 3 to 36 months) included clinical and ultrasound assessment. RESULTS: Preoperative assessment confirmed left-sided testicular hypotrophy 35 patients (88%). Thirty-eight varicoceles were stage 3, and 2 were stage 2. Testicular discomfort was present in 13 patients. Complete correction of the varicocele was achieved in 33 (83%). At a mean of 5 months after LV open repair in 7 patients confirmed a dilated cremasteric vein connecting to the IE veins. Ligation of the IE veins at the time of LV was associated with a persistent varicocele in 3 of 19 patients (16%), similar to the nonligated group, 4 of 21 patients (19%). Five patients (12.5%) had a mild hydrocele. The left testicular volume increased 30% to 50% in 28 patients (70%) at a median of 6.5 months after repair. Testicular atrophy did not occur in any patients. The majority of patients went home within 6 hours of surgery. CONCLUSIONS: The laparoscopic technique with preservation of the TA is an acceptable alternative to open surgical treatment of varicoceles. Further, it eliminates the risk of testicular atrophy and is the technique of choice when previous inguinal surgery has been performed. Ligation of IE veins was not associated with a decrease in the persistence of varicocele postoperatively.

Scrotal migration of a ventriculoperitoneal shunt

We report a case of scrotal migration of a ventriculoperitoneal (VP) shunt that presented as a hydrocele in an 18‐month‐old boy. The patient had a history of congenital hydrocephalus secondary to aqueductal stenosis requiring VP shunting at 1 month of age. He subsequently presented with painless progressive right scrotal swelling for 12 months with the distal segment of the shunt's peritoneal catheter palpable within the scrotum, which was confirmed by X‐ray imaging. Groin exploration for catheter removal and high ligation of the hydrocele were performed. Postoperatively, there was no recurrence of the hydrocele. We recommend that all infant patients with an implanted VP shunt undergo regular scrotal examinations at the neurosurgical clinic, and that early surgical intervention should be considered when a hydrocele is detected.     

Antegrade scrotal sclerotherapy for treating primary varicocele in children

OBJECTIVE: To evaluate the effectiveness and limitations of antegrade sclerotherapy (AS) for the treatment of primary varicocele in childhood. PATIENTS AND METHODS: From December 1996 to December 2004, 88 patients (mean age 13.3 years, range 9-18) with primary varicocele underwent AS (91 varicocele ablations in all). The indications for surgery were testicular pain (16 boys, 18%), a large varicocele with cosmetic implications, testicular hypotrophy (one) and in 71 (81%) the varicocele was detected incidentally during a routine physical examination; all were left-sided. According to the classification used by Tauber, 46 (52%) varicoceles were grade II and 42 (48%) grade III. The clinical and ultrasonography (US) results were evaluated over a median (range) follow-up of 11 (3-60) months, and the operative duration, X-ray exposure time, persistence rate of varicoceles and complications were compared with those using other techniques. RESULTS: In 11 patients there was a palpable difference in size between the testicles, but in only five (6%) was testicular hypotrophy (testicular volume (<75% testicular volume vs the normal side) confirmed by US. The mean (sem) operative duration for AS was 33.2 (2.14) min. In 16 (18%) patients it was necessary to expose a second or third vein because the first vein chosen was unsuitable for sclerotherapy. The mean operative radiation exposure was 2.18 (0.21) s. One patient (1%) was treated with a high ligature of the testicular vein (Palomo procedure) after initial unsuccessful AS, and was excluded from the analysis. Eighty-four (97%) patients were eligible for follow-up: six (7%) had a persistent varicocele (four grade II, two grade III), four of whom had repeat sclerotherapy successfully (no recurrence at follow-up). Fourteen (15%) patients had enlarged testicular veins only on US (varicocele grade 0). No patient developed a hydrocele after AS, There were complications after surgery in three (3%) patients (two superficial wound infections, one scrotal haematoma together with focal testicular necrosis). CONCLUSIONS: AS is an efficient minimally invasive surgical method for correcting varicoceles in older children, although the operative duration is sometimes longer than in adults, and surgery can be more difficult because of the smaller veins. Partial testicular necrosis, despite correct AS, is a very rare but serious complication.     

Results and complications of laparoscopic surgery for pediatric varicocele

BACKGROUND: The aim of this study was to evaluate the results and complications of laparoscopic varicocelectomy in children. METHODS: Over a 36-month period, 211 children underwent laparoscopic treatment of varicocele. Their ages ranged between 6 and 17 years; the varicocele was located on the left side in 209 cases (99.1%) and was bilateral in 2 (0.9%). In 195 patients the laparoscopic transperitoneal approach was used and in 16 retroperitoneoscopy was used. Thirty children (14.2%) underwent ligation of the veins alone, and 181 (85.8%) underwent ligation of testicular veins and artery. In 15 (7.1%) cases an additional procedure was applied during the same operation. RESULTS: Average operating time was 30 minutes and hospitalization about 24 hours. At an average follow-up of 26 months, there were 19 (9%) postoperative complications: 14 children had a left hydrocele, 3 children a scrotal emphysema, and 2 an umbilical granuloma. There were 5 recurrences of varicocele in our series: 2 (2 of 30, 6.6%) after the Ivanissevitch procedure, and 3 (3 of 181, 1.6%) after Palomo's. Testicular atrophy did not occur in any patient of this series. CONCLUSIONS: This preliminary experience shows that the results of the laparoscopic approach are comparable to those of the open approach. The ligation of testicular veins and artery is preferable to the ligation of the testicular veins alone. Hydrocele seems to be the most frequent postoperative complication and a potential problem, especially in children operated on with the Palomo procedure.     

Optimizing the operative treatment of boys with varicocele: sequential comparison of 4 techniques

PURPOSE: We compared 4 techniques of varicocele ligation in boys and young adolescents to determine the optimal operative treatment that avoids varicocele recurrence and postoperative hydrocele formation. MATERIALS AND METHODS: In 10 years a total of 128 varicocelectomies were performed sequentially in 121 boys and young adolescents with a mean age of 12 years using the laparoscopic, inguinal testicular artery sparing, standard Palomo (high mass retroperitoneal ligation) and modified Palomo approaches. The modified Palomo approach involved suprainguinal and retroperitoneal ligation of the veins and artery, and microsurgical sparing of the blue stained lymphatic pathway of the testis. Patients were followed a mean of 52 months. RESULTS: In the 19 boys in the laparoscopy group varicocele persisted in 10% and hydrocele developed in 5%. In the 21 patients who underwent inguinal surgery with artery preservation recurrent varicoceles were identified in 14% and no hydroceles were observed. In the 32 patients who underwent the standard Palomo procedure there was no palpable varicocele persistence or recurrence, while hydroceles developed in 12%. Of the 56 patients in the modified Palomo group varicocele recurred in 1 (2%) and there were no hydroceles. No testicular atrophy developed in any patient. CONCLUSIONS: Comparison of all 4 groups revealed significant differences in varicocele recurrence (p = 0.038) and hydrocele formation (p = 0.023). Pairwise group comparison showed that the modified Palomo technique resulted in a significant decrease in the incidence of postoperative hydrocele formation compared with the standard Palomo method (p = 0.015). This procedure can be recommended as the optimal surgical technique for varicocele treatment in males of this young age.     

Microsurgical inguinal varicocelectomy with delivery of the testis: an artery and lymphatic sparing technique.

Conventional techniques of varicocele repair are associated with substantial risks of hydrocele formation, ligation of the testicular artery, and varicocele recurrence. We describe a microsurgical technique of varicocelectomy that significantly lowers the incidence of these complications. The testicle is delivered through a 2 to 3 cm. inguinal incision, and all external spermatic and gubernacular veins are ligated. The testis is returned to the scrotum and the spermatic cord is dissected under the operating microscope. The testicular artery and lymphatics are identified and preserved. All internal spermatic veins are doubly ligated with small hemoclips or 4-zero silk and divided. The vas deferens and its vessels are preserved. Initially, we performed 33 conventional inguinal varicocelectomies in 24 men without delivery of the testis or use of a microscope. Postoperatively, 3 unilateral hydroceles (9%) and 3 unilateral recurrences (9%) were detected. For the next 12 cases 2.5x loupes were used resulting in no hydroceles but another recurrence (8%). We then performed 640 varicocelectomies in 429 men using the microsurgical technique with delivery of the testis. Among 382 men available for followup examination from 6 months to 7 years postoperatively no hydroceles and no cases of testicular atrophy were found. A total of 4 unilateral recurrent varicoceles (0.6%) was identified. The differences between the techniques in the incidence of hydrocele formation and varicocele recurrence are highly significant (p < 0.001). No wound infections occurred in any men. Four scrotal hematomas (0.6%), 1 of which required surgical drainage, occurred in the group with microsurgical ligation and delivery of the testis compared to none with the conventional technique. Preoperative and postoperative semen analyses (mean 3.57 analyses per patient) were obtained on 271 men. The changes in sperm count x 10(6) cc (36.9 to 46.8, p < 0.001), per cent motility (39.6 to 45.7%, p < 0.001) and per cent normal forms (48.4 to 52.10%, p < 0.001) were highly significant. The pregnancy rate was 152 of 357 couples (43%) followed for a minimum of 6 months postoperatively. Delivery of the testis through a small inguinal incision provides direct visual access to all possible avenues of testicular venous drainage. The operating microscope allows identification of the testicular artery, lymphatics and small venous channels. This minimally invasive, outpatient technique results in a significant decrease in the incidence of hydrocele formation, testicular artery injury and varicocele recurrence.     

Laparoscopic varicocelectomy: a simple technique for clip ligation of the spermatic vessels.

Less invasive laparoscopic surgery is replacing the conventional open operation for the treatment of several conditions. We performed laparoscopic clamping of the internal spermatic vessels in 12 subfertile patients to treat varicocele of the testis. Seven operations were performed with the patient under general anesthesia, whereas a local anesthetic was used in the 5 most recent patients. The internal spermatic vessels were successfully clipped in all 12 patients. Postoperative physical examination with a Doppler stethoscope showed that the venous reflux had disappeared in all patients. Semen quality was improved in 7 patients with a followup of 3 to 10 months. Neither hydrocele nor testicular atrophy was observed postoperatively. Laparoscopic varicocelectomy was effective and minimally invasive, especially when performed with the patient under local anesthesia.     

Intravenous methylene blue venography during laparoscopic paediatric varicocelectomy

Introduction

One of the challenges of varicocele surgery is to prevent hydrocele formation while still ensuring success. Methylene blue has been used to identify and preserve lymphatic vessels, and venography has been a standard component of sclerotherapy and percutaneous retrograde techniques. The authors have combined both approaches during laparoscopic varicocelectomy and report their experience.

Methods

A prospective study was performed of adolescents with idiopathic varicocele and spontaneous venous reflux on Doppler ultrasound. A pampiniform plexus vein was cannulated via scrotal incision before creating the pneumoperitoneum. A mixture of methylene blue and Omnipaque™ was injected into the pampiniform plexus with fluoroscopic screening. Laparoscopic selective vein ligation was then performed using 5 mm endoscopic clips or a bipolar vessel sealing device such as Plasmakinetic™ or Ligasure™. Venography was repeated to confirm complete ligation of the internal testicular veins. Patients were followed-up at 3, 6, and 9 months post-surgery with clinical examination and Doppler ultrasound. Data are presented as median (interquartile range).

Results

Twenty-four patients underwent laparoscopic selective vein ligation with venography and methylene blue injection. The median age was 14.7 (14.6–15.7) years. The recurrence rate was 12%. No patients developed a hydrocele. The length of surgery was 120 (100–126) minutes.

Conclusion

Intra-operative intra-venous methylene blue injection and venography helps to identify venous duplications of the internal testicular veins and enhances the success rate of laparoscopic selective vein ligation. This approach prevents hydrocele formation but has a 12% recurrence rate, which appears to be higher than some techniques described in the literature.     

Evaluation of 100 laparoscopic varicocele operations with preservation of testicular artery and ligation of collateral vein in children and adolescents

OBJECTIVES: To introduce a useful technique for identifying any collateral veins during laparoscopic varicocele operation and to evaluate our long-term results with this technique after 100 cases. METHODS: A new method was used to detect an incidental collateral vein. During surgery the patient was placed in anti-Trendelenburg position after introducing laparoscopic instruments until the dilated scrotal varicose filled up with blood. The main spermatic vein was then grasped atraumatically and the blood was pressed out manually from the scrotum. During this manoeuvre any existing collateral vein/veins became dilated and could be easily identified. The dilated spermatic vein and also any collateral vessel were first prepared then clipped. RESULTS: Out of the 100 patients, collateral veins were detected and ligated in 19 cases. In 15 cases a single collateral, in 4 cases two collaterals, and in the remaining 81 children no collateral veins were found. The testicular artery was identified in all operations as a pulsatile vessel. At a mean of 24 months (range 6-60 months) follow-up recurrence occurred in one patient and in five children hydrocele developed postoperatively. Testicular atrophy and severe intra- or postoperative complication did not occur in any patient of this series. CONCLUSION: The identification of incidental collateral vein by this method and preservation of the testicular artery resulted in a very good success rate in children and adolescents treated by laparoscopic varicocele operation.     

传统经腹股沟、显微技术和腹腔镜精索静脉结扎术后并发症发生率的对比研究

目的探讨经腹股沟切口显微精索静脉结扎术与传统经腹股沟、腹腔镜技术精索静脉结扎术的安全性。方法回顾性分析自2005年6月至2006年12月间收治的118例精索静脉曲张患者（156侧）3种不同术式术后并发症的发生率，其中60例采用经腹股沟途径显微技术，40例采用传统经腹股沟技术，18例采用腹腔镜精索静脉结扎术。随访时间6～12个月。结果显微技术、传统经腹股沟途径、腹腔镜技术精索静脉结扎术后阴囊水肿发生率分别为0％（0／76）、6％（3／50）、3．4％（1／30）；复发率分别为1．67％（1／76）、7．5％（4／50）、6．7％（2／30），三组均未见睾丸萎缩。经统计学分析，显微技术阴囊水肿发生率低于另外两组（P〈0．05）。复发率及睾丸萎缩发生率在三组间无统计学差异。结论较传统经腹股沟途径和腹腔镜技术精索静脉结扎术，经腹股沟途径显微技术未发生术后阴囊水肿，曲张复发率低，是一种值得推广的安全术式。     

Melanoma of the penis, scrotum and male urethra: a 40-year single institution experience

PURPOSE: Genitourinary melanoma is rare and classically associated with a poor prognosis. We describe our experience with 10 patients with penile or urethral involvement. In addition, we present what is to our knowledge the largest reported series of melanoma of the scrotum (6 cases). MATERIALS AND METHODS: We reviewed the records of 16 men who presented consecutively to our institution with genitourinary melanoma between 1962 and 2000. Clinical and pathological characteristics were assessed, including Breslow thickness, primary surgical intervention and clinical course. RESULTS: Of 10 patients with penile or urethral melanoma 1997 American Joint Committee on Cancer melanoma pathological stage was T1 (depth less than 0.75 mm) in 4, T2 (0.75 to 1.5 mm) in 3 and T3 (1.51 to 4 mm) in 3. Only 1 of 4 patients with clinically palpable inguinal nodes had inguinal metastases at lymphadenectomy (BILND) and 3 who underwent prophylactic superficial BILND had negative findings. In 7 patients with T1-2N0M0 disease there were no local recurrences after wide local excision (WLE) or partial penectomy at a median followup of 35 months. Six of 7 men were rendered disease-free. One patient died of melanoma that developed at a second primary site. The 3 patients with T3 tumors who underwent partial (2) or radical (1) penectomy with or without BILND died of disease (2) or had progression (1). In all patients with penile melanoma the 5-year actuarial disease specific and recurrence-free survival rates were 80% and 60%, respectively, at a median followup of 39 months (range 20 to 210). Six patients with scrotal melanoma were treated with WLE without local recurrences. Three of the 6 patients had palpable inguinal nodes, of whom 2 died after chemotherapy for unresectable disease and 1 died of other causes 51 months after negative BILND. The 3 men with clinically negative groins who did not undergo prophylactic BILND had distant (1) or regional (2) metastases and died of disease. In patients with scrotal melanoma the 5-year actuarial disease specific and recurrence-free survival rates were 33.3% and 33.3%, respectively, at a median followup of 36 months. CONCLUSIONS: Partial penectomy or WLE provided effective local control for low stage penile or urethral melanomas and all scrotal lesions. Patients showing clinically positive, proven metastasis died despite appropriate surgical procedures and multi-agent chemotherapy. Prophylactic modified inguinal lymphadenectomy should be considered in select patients with penile, scrotal and anterior urethral melanoma.     

Recurrences in surgical stage I nonseminomatous germ cell tumors of the testis

A retrospective analysis of patients with surgical stage I nonseminomatous germ cell tumors of the testis was done in an attempt to define the pathogenesis of treatment failure. Of 138 patients 126 (91 per cent) remain free of disease, with a median followup of 5 or more years, and 12 (9 per cent) suffered relapse an average of 9 months after orchiectomy and retroperitoneal lymph node dissection. The majority of recurrences were in the lungs. Of 12 patients who had recurrence 6 were salvaged and are alive without evidence of disease 3 or more years after the second complete remission. A history of scrotal surgery or scrotal violation, the extent of the primary tumor and the presence of sarcomatous elements in the primary were not statistically significant risk factors in this study. A higher recurrence rate with embryonal carcinoma than with teratocarcinoma was not statistically significant.
