The analysis of prognostic factors on postsurgical pyuria of benign prostatic hypertrophy

The outcome of postsurgical pyuria in benign prostatic hypertrophy was studied in 87 patients, and the factors that might affect the outcome were determined. No significant differences were found between operation method and duration until normalization of pyuria, which was 75.5 +/- 46.0 days for transurethral resection of the prostate, 72.7 +/- 30.6 days for suprapubic prostatectomy and 69.3 +/- 32.7 days for retropubic prostatectomy. Prognostic factors were statistically analyzed preoperatively, at operation, and postoperatively. The definite prognostic factors were preoperative diabetes mellitus, preoperative pyuria, preoperative bacteriuria, and postoperative hypoproteinemia. The probable prognostic factors were old-age, preoperative indwelling catheters, heavy prostate tissue, postoperative bacteriuria, postoperative anemia and postoperative complications.     

Morbidity of radical perineal prostatectomy following transurethral resection of the prostate

Radical prostatectomy in patients who have had prior transurethral resection of the prostate has been reported to result in significant morbidity. From 1974 to 1982, 30 patients who had had previous transurethral resection of the prostate underwent radical perineal prostatectomy for localized prostatic cancer. Operative time and blood loss were similar to a group of patients who had not had prior transurethral resection of the prostate. Over-all, 3 patients (10 per cent) had total incontinence and 3 (10 per cent) had stress incontinence requiring a pad or device. No patient undergoing radical prostatectomy less than 4 weeks or more than 4 months after transurethral resection of the prostate had postoperative incontinence. When radical perineal prostatectomy was performed between 4 weeks and 4 months after transurethral resection of the prostate the incidence of incontinence was 50 per cent. Five patients experienced prolonged perineal urinary drainage, all but 1 of whom healed spontaneously. Of the 6 patients with incontinence 3 had prolonged drainage. No patient had a rectal injury and there was no operative mortality. Two patients died without cancer and 1 has evidence of disease recurrence. We conclude that radical prostatectomy may be performed safely with acceptable morbidity following transurethral resection of the prostate and that if 4 weeks has elapsed since resection it might be advantageous to wait 4 months before performing radical surgery to lessen the risk of incontinence.     

Radical retropubic prostatectomy after transurethral prostatic resection

In 16 patients who underwent radical retropubic prostatectomy because of adenocarcinoma of the prostate after previous transurethral resection, the difficulty of the operation, the morbidity rate, and the survival time were evaluated. Eleven patients had tumours staged A2, 5 patients tumours staged B1. Duration of the operation and blood loss were almost similar to the group of patients who had not had prior transurethral resection of the prostate. The impotence rate was 100% due to difficulties preparing and preserving the neurovascular bundle. Only 1 patient had stress incontinence. One patient died after 2 years with rapid tumour progression, 1 patient shows local recurrence. Radical prostatectomy may be performed safely with an acceptable morbidity rate following transurethral resection of the prostate.     

Rectourethral fistula after radical prostatectomy: Transperineal repair in jack-knife position

Background: Rectourethral fistula is a rare complication of radical prostatectomy. Risk factors include history of pelvic irradiation, cryotherapy, intraoperative rectal injury or transurethral resection of the prostate. Diagnosis of rectourethral fistula requires a high index of suspicion, and complete work-up with endoscopy and imaging studies. The majority of patients require operative intervention, with approaches ranging from transabdominal, transrectal, transanal, and transperineal routes. Method: We report two patients with rectourethral fistula after radical prostatectomy. The first patient was a 59-year-old man who underwent an uncomplicated laparoscopic radical prostatectomy for early prostate cancer in another hospital. The second patient was a 64-year-old man who had local recurrence after cryotherapy for prostate cancer. He underwent salvage radical prostatectomy in a private hospital, which was complicated by intraoperative rectal injury. Results: In both patients, the rectourethral fistulae were successfully repaired with a transperineal approach in the prone jack-knife position. Conclusion: We found that the transperineal approach in the prone jack-knife position offered excellent exposure, allowed versatile surgical manoeuvres and produced successful repair with good continence outcomes.     

Pathological T0 prostate cancer without neoadjuvant therapy: clinical presentation and follow-up

INTRODUCTION AND OBJECTIVES: Radical prostatectomy is a standard therapy for patients with prostate cancer diagnosed by prostatic needle biopsy, prostate cytology, transurethral resection of the prostate or prostatectomy. In a small group of patients no tumour can be found in the radical prostatectomy specimen. These cases are classified as stage pT0. The aim of this study was to evaluate the clinical presentation of this entity and their prognosis. MATERIAL AND METHODS: In a nation-wide database the clinical data of 3609 patients with prostate cancer were collected. 28 patients (0.8%) were staged as pT0 in the radical prostatectomy specimen. The data included age, prostate specific antigen (PSA), and pathological report at diagnosis, histology of the radical prostatectomy specimen and follow-up data. RESULTS: The diagnosis was made by TURP (transurethral resection of the prostate) in 15, prostatectomy in 2, needle biopsy in 11, and cytology in 2 patients. For patients who underwent TURP or prostatectomy the preoperative staging was T1a in 10 and T1b in 5 cases. 12 patients diagnosed by biopsy or cytology were classified T2a and one patient after biopsy as T2b. 9 patients had a GI- and 19 a GII-tumour, GIII-pattern was not represented. The mean age at diagnosis was 64.7 years (range 53-79 years). The PSA at the time of diagnosis was <4ng/ml in 8 cases; 4-10ng/ml in 16 cases and >10ng/ml in 4 patients. One patient presented with a micrometastasis in a single lymph node. Median follow-up was 62 months (19-150). All patients had undetectable PSA levels following surgery. No patient presented with clinical or biochemical progression. One patient died with no evidence of disease at 133 months after radical prostatectomy. CONCLUSIONS: None of the clinical parameters had a strong association with a pathologically proven T0 situation after radical prostatectomy in this setting. Interestingly no patient had a high-grade tumour. None of the patients classified as pT0 had a biochemical or clinical relapse during follow-up.     

A randomized controlled trial comparing transurethral resection of the prostate,contact laser prostatectomy and electrovaporization in men with benign prostatic hyperplasia: urodynamic effects

PURPOSE: We compared urodynamic and uroflowmetry improvements in men with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (BPH) after transurethral prostate resection, contact laser prostatectomy and electrovaporization. MATERIALS AND METHODS: A prospective randomized controlled trial was performed in men with lower urinary tract symptoms suggestive of BPH who met the criteria of the International Scientific Committee on BPH, had a prostate volume of between 20 and 65 ml., and a Sch?fer obstruction grade of 2 or greater. Before and 6 months after treatment urodynamics and free uroflowmetry were performed. RESULTS: A total of 50, 45 and 46 men were randomized to transurethral prostate resection, laser treatment and electrovaporization, respectively. Baseline characteristics were similar in the 3 groups. Detrusor contractility did not change in any of the treatment groups. The average maximum free flow rate increased by a factor of 2.4 after transurethral prostate resection, 2.5 after laser prostatectomy and 2.4 after electrovaporization. The Sch?fer obstruction grade decreased by a factor of 0.3 in all groups. Obstruction (Sch?fer grade greater than 2) was not noted after transurethral prostate resection or electrovaporization but it was evident in 2 patients after laser prostatectomy. Effective capacity increased by a factor of 1.5 or more. The incidence of detrusor instability was decreased by half in all groups. The incidence of significant post-void residual urine volume decreased in all groups. CONCLUSIONS: There were no significant differences in the improvement in urodynamic and uroflowmetry parameters 6 months after treatment when comparing transurethral prostate resection, contact laser prostatectomy and electrovaporization in men with lower urinary tract symptoms suggestive of BPH.

Urethral stricture after TURP and transvesical prostatectomy]

In an attempt to elucidate factors predisposing to the occurrence of urethral stricture after transurethral resection of the prostate, we performed a prospective follow-up of 178 patients over 12-20 months. We took account of 11 factors that we considered important. Urethral strictures developed in 14.04% of the patients. The resection operations were carried out by five different surgeons, who had different rates of stricture. The only one of the 11 factors studied that was found to involve a statistically significant risk was the presence of an indwelling catheter for more than 3 days. No other factor influenced the result. This patient group was compared with a group of 73 patients followed up for 12-60 months following transvesical prostatectomy. In this group only one stricture (1.36% incidence rate) was observed retrospectively. It seems that urethral ischaemia might increase the risk of urethral stricture. Urethral injuries are considerably less frequent with open prostatectomy. Therefore, we recommend transvesical prostatectomy for pronounced prostatic hyperplasias.     

The course of pyuria after transurethral resection of the prostate and factor analysis of its duration

The course of pyuria and bacteriuria was reviewed in 54 patients undergoing transurethral resection of prostate. Pyuria, which was seen in all cases, lasted for 70.1 +/- 24.7 days and bacteriuria defined as more than 10(4)/ml occurred in 16 patients (30%) postoperatively. To analyze the factors affecting the duration of pyuria, we utilized Hayashi's multidimensional quantification I theory. The factors included age, serum protein, preoperative indwelling catheter, preoperative urinary tract infection, resected weight, postoperative infection, the duration of postoperative indwelling catheter, and the way of antibacterial prophylaxis. The most important factor was resected weight (range 42.8 days), the second was postoperative infection (range 23.9 days) and the third preoperative infection (range 20.9 days). The other factors had no significance. Our analysis showed good correlation between the observed and predicted duration of pyuria (r = 0.82, p less than 0.005).

The predictive accuracy of staging transurethral resection of the prostate in the management of stage A cancer of the prostate: a comparative evaluation

The role of staging transurethral resection of the prostate in the management of stage A prostate cancer is controversial. The accuracy of staging transurethral resection, A1/A2 substaging and probability of progression tables for predicting cancer progression was evaluated in untreated patients with stage A adenocarcinoma of the prostate who were followed for at least 5 years. Survival free of disease was predicted correctly in 93% of 52 patients who underwent staging transurethral resection of the prostate, 92% of 96 with the probability tables and in 85% of 96 using a common criteria for A1 and A2 substaging. Staging transurethral resection of the prostate upgraded patient risk in 7% of the low risk patients predicted by the probability tables and 14% of the stage A1 cancer patients. Staging transurethral prostatectomy and the probability of progression tables were more accurate in predicting survival free of disease than the A1/A2 substaging system. Comparison of the predictive accuracy of staging transurethral prostatectomy to that of the probability of progression tables showed no significant difference. There was no additional benefit from combining the 2 methods. When the probability of progression tables are used to predict cancer progression it may be unnecessary to use staging transurethral resection of the prostate in the patient with stage A prostate cancer.     

Postoperative pyuria after TUR-P: the study of postoperative pyuria by using NFLX

The postoperative duration of pyuria was studied in 35 patients who underwent transurethral resection of the prostate (TUR-P). The average postoperative duration of pyuria was 58.0 +/- 23.6 days. The age over 70 years, preoperative indwelling of urethral catheter and the preoperative urinary tract infection did not make the duration of pyuria longer. The volume of resected prostatic tissue over 20 g and the existence of diabetes mellitus make it significantly longer. It is effective and safe to use a low-dose antibacterial agent such as NFLX which has a broad spectrum and hardly develops bacterial resistance after TUR-P. It is suggested unnecessary to change the anti-bacterial agent even when pyuria continues.     

Anaesthesia and prostate surgery

OBJECTIVES: To review the current data about anaesthetic management in prostate surgery with special regards on analysis and prevention of specific risks, appropriate anaesthetic procedure keeping with surgery and patient, recognition and treatment of adverse events. DATA SOURCES AND EXTRACTION: The Pubmed database was searched for articles (1990-2004) combined with references analysis of major articles on the field. DATA SYNTHESIS: It is strongly recommended to settle germfree urine in the preoperative period. The thromboembolic risk of radical retropubic prostatectomy for cancer parallels lower abdomen oncologic surgery and is prolonged. Preoperative evaluation of cardiovascular, respiratory, neurological and metabolic comorbidity is a source of prognostic information and an essential tool in the management of elderly patients with prostate disease. Extreme patient positioning applied in prostate surgery induces haemodynamic and respiratory changes and are associated with severe muscular and nervous injuries. The laparoscopic access for radical prostatectomy is a growing alternative to the open surgical procedure. Acute normovolaemic haemodilution is a consistent and cost-effective blood conservation strategy in reducing allogenic blood transfusion for radical retropubic prostatectomy. Whether open transvesical or transurethral prostatectomy for treatment of benign hypertrophy depends on the size of the gland: transurethral resection is safe up to 80 g. Intrathecal anaesthesia with a T9 cephalad spread of sensory block, produces adequate conditions for transurethral prostatectomy and allows a rapid diagnosis of irrigating fluid absorption syndrome. In spite of recommended preoperative antibiotic prophylaxis, bacteriemias are frequent during transurethral prostate resection.     

Prostatic cancer after transurethral resection for benign prostatic hypertrophy]

Five cases of prostatic cancer developed after transurethral resection of prostate for benign hypertrophy are reported. Duration of transurethral resection of prostate (TUR-P) to diagnosis of prostatic cancer ranged from one year and seven months to seven years and two months, on average four years and seven months and frequency of prostatic cancer after TUR-P was estimated at 1.2%. Four of five patients complained of macroscopic hematuria. The cystourethrogram showed the mass protruded in the dilated prostatic urethra or bladder-neck in four patients (80%), a remarkable finding, and four cases were at stage D. Risk of development of prostatic cancer is not decreased even after prostatectomy and prostatic carcinoma diagnosed after TUR-P often advances in stage. Therefore, periodical examinations of the patients who had a prior prostatectomy are very important.     

Study of the long-term administration of ofloxacin to the patients following transurethral resection of the prostate]

The present study was undertaken to evaluate the clinical efficacy of long-term administration of ofloxacin (OFLX) to the patients following transurethral resection of the prostate. The patients were randomly divided into two groups: A and B. All the patients were administered flomoxef (FMOX) intravenously for 3 days following transurethral resection of the prostate (TUR-P). In group A, 100 mg of OFLX twice daily was thereafter administered for 4 to 15 weeks to 22 patients until they showed an improvement in pyuria. In group B, which served as a control, neither OFLX nor any other antibiotics were administered to 26 patients until they showed an improvement in pyuria. No patients complained of urination trouble due to infection. At the same time, cultures of bacillus in the urine were also examined 4 days, 7 days and 2 weeks after TUR-P with these two groups. The mean days necessary for the improvement of pyuria were 64.9 +/- 20.5 in group A, 66.3 +/- 18.4 in group B. At 2 weeks after TUR-P, bacillus in the urine were negative in 19/22 patients in group A, and 14/26 in group B. Chi-square test showed significance for these two groups. Accordingly, OFLX was useful for bacillus in the urine, but OFLX was not so useful for shortening the continuance of pyuria of post TUR-P. No patients complained of nausea or any other complications during the study.

Surgical outcomes for men undergoing laparoscopic radical prostatectomy after transurethral resection of the prostate

PURPOSE: We reviewed outcomes for men with a history of transurethral prostate resection who underwent laparoscopic radical prostatectomy for prostate cancer. MATERIALS AND METHODS: Between January 26, 1998 and December 2006, 3,061 men underwent laparoscopic radical prostatectomy at our institution. A retrospective review showed that 119 had a history of transurethral prostate resection. These men were compared to randomized matched controls with regard to operative and postoperative outcomes. The matching criteria used to randomly select patients were clinical stage, preoperative prostate specific antigen and biopsy Gleason score. RESULTS: Mean +/- SD age in the groups with and without transurethral prostate resection was 66.2 +/- 5.6 and 60.7 +/- 7.0 years, respectively (p <0.01). Mean estimated blood loss, transfusion rate, pathological prostate volume and reoperation rate were statistically similar between the groups. Mean length of stay for the groups with and without transurethral prostate resection was 6.5 +/- 3.0 and 5.29 +/- 2.3 days, respectively (p <0.01). Mean operative time for the groups with and without transurethral prostate resection was 179 +/- 44 and 171 +/- 38 minutes, respectively (p = 0.02). Positive margins were seen in 21.8% and 12.6% of the patients with and without transurethral prostate resection, respectively (p = 0.02). A total of 64 complications were seen in patients with a history of transurethral prostate resection compared to 34 in those without such a history (p <0.01). CONCLUSIONS: We report that patients with a history of transurethral prostate resection who undergo laparoscopic radical prostatectomy have worse outcomes with respect to operative time, length of stay, positive margin rate and overall complication rate. This subset of patients should be made aware of these potential risks before undergoing laparoscopic radical prostatectomy.     

Can stage A1 tumor extent be predicted by transurethral resection tumor volume, per cent or grade? A study of 64 stage A1 radical prostatectomies with comparison to prostates removed for stages A2 and B disease

We studied 64 totally embedded radical prostatectomy specimens of stage A1 prostate cancer. The transurethral resection specimens were studied and compared to previously studied stages A2 and B cancer in which tumor volumes also were calculated. At radical prostatectomy 6% of the specimens had no residual cancer, 74% had minimal cancer and 20% had substantial cancer. Although most stages A2 and B tumors were larger, there was overlap among all stages. Transurethral resection tumor volume, per cent and grade were not statistically correlated with either radical prostatectomy residual tumor volume, or whether tumor was classified as minimal or substantial. Gleason sum 2 to 4 versus 5 to 7 tumor on transurethral resection showed no difference in predicting radical prostatectomy residual tumor or minimal versus substantial tumor status. Because 20% of all stage A1 cancers have substantial tumor at radical prostatectomy unpredictable by transurethral resection, radical prostatectomy remains an option for young men with stage A1 prostate cancer.     

The prophylactic use--or misuse--of antibiotics in transurethral prostatectomy

One hundred non-infected patients undergoing transurethral prostatectomy were randomized prospectively into a controlled study to determine the influence of a prophylactic aminoglycoside (kanamycin) on the clinical course. In the non-risk patient prophylactic kanamycin had no beneficial influence on the incidence of bacteriuria, fever or length of hospitalization. Its use was associated with the development of a resistant Pseudomonas super infection in 1 patient. Prophylactic kanamycin did not protect the patient with carcinoma of the prostate from bacteriuria. There was no identifiable advantage in the use of routine prophylactic kanamycin in the uninfected, non-risk patient who was undergoing elective transurethral prostatectomy.
