Between 1981 and 1985 we performed 32 ureteropyeloplasties on 29 infants and children with ureteropelvic junction obstruction. The posterior lumbotomy incision was used in 14 cases and proved to offer distinct advantages when compared to the anterior and flank incisions. The surgical technique is described in detail and the advantages are discussed. 相似文献

BACKGROUND: The purpose of the present study was to comprehensively assess the results of surgical management of pelvi-ureteric junction (PUJ) obstruction using lumbotomy as the surgical approach. METHODS: Records of 36 consecutive patients with unilateral PUJ obstruction who underwent pyeloplasty in the last 5 years were reviewed retrospectively. The investigations included renal function tests, ultrasound and serial renal diuretic scans. A micturating cystourethrogram was also done whenever indicated. A dismembered pyeloplasty via lumbotomy was the only surgical approach considered. Thirteen patients had a right pyeloplasty while 23 had a left pyeloplasty. Mean age at diagnosis was 57 months in 31 patients while five were antenatally diagnosed (range 1 month-12 years). Age at surgery ranged from 1 month to 12 years with a mean of 59.9 months. Nine children underwent surgery in infancy. Six patients had a preoperative percutaneous nephrostomy (PCN) placement, five for poorly functioning kidneys (less than 10% split renal function) and one for oliguria. Records were reviewed for age at diagnosis, age at surgery, duration of surgery, preoperative and postoperative split renal function. RESULTS: The follow-up period in the present study ranged from 9 months to 68 months with a mean of 44.9 months. Mean duration of surgery was 78 min of the group as a whole but in PCN patients it was significantly more (100 min vs 71.3 min). Fourteen patients had an improvement in split renal function noticed at 3 and 6 months postoperatively, 17 patients had no change while one patient had a deterioration of split renal function. Four patients had a solitary functioning kidney and in all of these glomerular filtration rate improved postoperatively. Hospital stay was on the average 7.45 days with a range of 6-10 days. However, when a double-J (D-J) stent was used across the anastomosis and the uretero-vesical junction (transrenal D-J stenting), the mean stay was reduced to 3 days. All patients returned to full oral feeds by postoperative day 1. No incidences of wound related problems were encountered. CONCLUSIONS: Pyeloplasty results in predictably good outcome in paediatric PUJ obstruction whenever indicated. The lumbotomy approach avoids muscle cutting, thereby minimizing complications related to wound and assisting with faster recovery. Keeping a double-J (D-J) stent across the anastomosis and the uretero-vesical junction (transrenal D-J stenting) reduces hospital stay. 相似文献

PURPOSE: To describe our experience and operative technique for retroperitoneoscopic nephrectomy for pyonephrosis and to compare the results with those of open surgery. PATIENTS AND METHODS: Since October 1998, 23 successful retroperitoneoscopic nephrectomies for pyonephrosis were performed in our institution (Group A). These patients were compared with 23 patients, matched by age, sex, and body weight, who underwent classic lumbotomy for pyonephrosis (Group B). The two groups were compared in terms of operative time, blood loss, hospital stay, wound complications, and time of return to previous occupation. RESULTS: All the features studied except operative time were significantly different in favor of laparoscopy. CONCLUSION: Although technically difficult, retroperitoneoscopic nephrectomy for pyonephrosis is feasible. The extraperitoneal approach allows direct access to the renal hilum and helps avoid spillage of pus into the peritoneum. 相似文献

Between July 1978 and December 1985, 100 patients underwent an operation on the kidneys and ureter through the dorsal lumbotomy approach. A total of 12 patients underwent dismembered pyeloplasty for ureteropelvic junction obstruction. Compared to patients who underwent an operation via the standard flank incision, these 12 patients had significantly shorter hospitalization and fewer doses of analgesics. The treatment demonstrated improved cost-effectiveness. Similar advantages were noted in the remaining patients in whom removal of calculi (78), open renal biopsy (5), simple nephrectomy (4) and removal of a foreign body in the ureter (1) were done through the dorsal lumbotomy approach. We appeal for a renaissance of the dorsal lumbotomy approach in urological teaching and practice. 相似文献

PURPOSE: Laparoscopic pyeloplasty offers similar success rates compared to open surgery. However, the advanced laparoscopic skills required may limit its widespread application. In select patients the dorsal lumbotomy approach can provide similar postoperative advantages to minimally invasive surgery. We analyze the perioperative management of laparoscopy vs dorsal lumbotomy for the repair of ureteropelvic junction obstruction. MATERIALS AND METHODS: In a retrospective review 13 patients who underwent dorsal lumbotomy pyeloplasty were compared to 19 patients who underwent laparoscopic pyeloplasty between 1998 and 2003. Preoperative confirmation of obstruction was obtained through excretory urogram or renal Lasix scan. All 13 patients undergoing dorsal lumbotomy had a dismembered pyeloplasty. Of the 19 laparoscopic cases 16 had a dismembered pyeloplasty and 3 had a Fenger procedure. Average followup was 12 months for the open group and 13.3 months for the laparoscopic group. Postoperative results were evaluated with excretory urogram or renal Lasix scan as well as subjective outcomes by the patients. RESULTS: Operative time was slightly longer for the laparoscopy group at 231 minutes vs 200 minutes. Estimated blood loss and postoperative morphine requirements were also similar. Hospital stay was 3.3 days for the dorsal lumbotomy group compared to 2.4 for the laparoscopy group. The overall success rate for the laparoscopic group was 94.7% compared to 100% for the dorsal lumbotomy group. Each group had 1 complication, paresthesia of anterior/medial thigh that resolved by 6 months. CONCLUSIONS: Our preliminary results show that a dismembered dorsal lumbotomy pyeloplasty is comparable to laparoscopic dismembered pyeloplasty with regard to intraoperative and postoperative hospital course. 相似文献

Objective:
Dismembered pyeloplasty through dorsal lumbotomy to correct ureteropelvic junction obstruction is mainly successfully performed in children under 5 years old for technical reasons. We compared children who underwent dorsal lumbotomy by age group (<5 vs. ≥5 years old) to determine if the surgical success and long-term results were comparable.Materials and Methods:
We retrospectively reviewed the charts of 134 children undergoing a pyeloplasty. Group 1 consisted of children <5 years old (n = 90) and Group 2 consisted of children ≥5 years old. Patients’ characteristics, as well as hospital stay, narcotic use, radiologic follow-up and success rate, were compared. Success was defined by absence of symptoms and ≥50% reduction in renal pelvis anteroposterior diameter and/or scintigraphic normalization of the drainage T1/2 when obtained. Univariate analysis was performed to compare the groups.Results:
Mean age (years) and weight (kg) at surgery for Groups 1 and 2 were 1/8 kg and 11/35 kg, respectively. Mean operative time was 98 minutes versus 120 minutes, respectively; mean hospital stay was 2.5 days for both groups and analgesia requirement was 50% higher in Group 2. A Pippi-Salle stent was used in 90% (n = 120) of cases. Mean follow-up was 26 months and the success rate was 89% and 90% for Groups 1 and 2, respectively.Conclusion:
Our study showed comparable success rates. We can infer that, as a technique, dismembered pyeloplasty is effective and safe in the younger and older children. 相似文献14.
The authors compare two successive series of surgically treated phaeochromocytomas. The first series consisted of 18 patients treated by laparotomy. During the immediate postoperative course, one patient died, 10 patients developed complications and 11 patients required blood transfusion. One patient died later from a recurrence. In the following series, 17 patients were operated by lumbotomy, which was bilateral in three cases. The mortality was nul, two patients developed complications and three patients required transfusion. Although successive series must be compared very cautiously, lumbotomy is justified by the surgical simplicity and the decreased morbidity. It is only possible as a result of the progress in medical imaging, particularly computed tomography, meta-iodobenzylguanidine isotope scans and magnetic resonance imaging. 相似文献

Extended transsphenoidal approach with submucosal posterior ethmoidectomy for parasellar tumors. Technical note. 总被引:13,自引:0,他引:13
The authors have developed an extended transsphenoidal approach with submucosal posterior ethmoidectomy for resection of tumors located in the cavernous sinus or the suprasellar region that are difficult to remove via the conventional transsphenoidal approach. Surgery was performed using this approach in 14 patients with large pituitary adenomas, three patients with craniopharyngiomas, and one patient with a meningioma of the tuberculum sellae. The submucosal dissection of the nasal septum used in the conventional transsphenoidal approach was extended to the superior lateral wall of the nasal cavity to expose the bony surface of the superior turbinate lying under the nasal mucosa. Submucosal posterior ethmoidectomy widened the area visualized through the conventional transsphenoidal approach both superiorly and laterally. This provided a safer and less invasive access to lesions in the cavernous sinus or the suprasellar region through the sphenoid sinus. Using this approach the authors encountered no postoperative complications, such as olfactory disturbance, cranial nerve palsy, or arterial injury. In this article the authors present the surgical methods used in this approach. 相似文献

The time to full mobility and total analgesic requirements have been assessed in 40 patients undergoing renal surgery by the oblique loin incision or the posterior lumbotomy approach. By these criteria the lumbotomy group fared better than patients who had oblique incisions. We consider lumbotomy to be a valuable incision which should be in the repertoire of every urologist. 相似文献

Objective
The object of this study was to better define the relevant anatomy and innervation of the anterolateral abdominal wall musculature seeking to avoid abdominal wall complication after open donor nephrectomy. We dissected four cadavers and retrospectively assessed donor ultrasonographic imaging of anterolateral abdominal muscle atrophy after donor nephrectomy with a lumbotomy incision.Methods
Anatomic study was performed on four cadavers using bilateral dissections. The 8th, 9th, 10th, 11th, and 12th (subcostal) intercostal nerves were dissected from the intercostal space to the rectus sheath. With the experience gained from anatomic study, we performed 40 living donor incisions 1.5 to 2 cm medial to the tip of 12th rib, toward the lateral border of the rectus muscle and the umbilicus. Donors were invited to the hospital at 1 year postoperative to examine abdominal wall complications. Ultrasonography (USG) was performed to assess the thickness of the abdominal wall muscles bilaterally to ascertain whether there was atrophy.Results
All distal intercostal nerves ran as multiple mixed segmental nerves, communicating with each other widely within the neurovascular plane. The thick 12th nerve was located at 1.5 to 2 cm medial and under the tip of the 12th rib, running to the suprapubic area. Postoperative USG confirmed that the mean percent thickness of the abdominal muscles of the operative side was not significantly different from the other side (P < .05).Conclusion
Most significant intercostal nerve contributions to the anterolateral abdominal wall arise from T12. Damage to the intercostal nerves will be minimal if the lombotomy incision is performed above the safe line between the tip of the 12th rib and the umblicus. 相似文献19.
Skull base surgery has gone through significant changes with the development of extended endoscopic endonasal approaches over the last decade. Initially used for the transphenoidal removal of hypophyseal adenomas, the endoscopic transnasal approach gradually evolved into a way of accessing the whole ventral skull base. Improved visualization, avoidance of brain retraction, the ability to access directly tumours with minimal damage to critical neurosurgical structures as well lack of external scars are among its obvious benefits. However, it presents the surgeons with a number of challenges, including the need to deal endoscopically with potential arterial bleeding, complicated reconstruction requirements as well as the need for a true team approach. In this review drawing from our experience as well as published series, we present an overview of current indications, challenges and limitations of the expanded endonasal approaches to the skull base. 相似文献
