Reluctance over right-sided retroperitoneoscopic living donor nephrectomy: justified or not?

UNLABELLED: We retrospectively compared perioperative donor outcomes and early complication rate of right- and left-sided retroperitoneoscopic living donor nephrectomy (RLDN). METHODS: From November 2001 to April 2006, we performed 118 RLDN. Including 24% (n = 28) right-sided RLDN and 76% (n = 90) left-sided RLDN. Perioperative results and the rate of adverse events were compared for both sides. RESULTS: We observed no significant difference in operation time, blood loss, warm ischemia time, or postoperative creatinine levels between right- and left-sided kidney donors. RLDN was successfully performed in 116 of 118 donors. One donor in each group had to be converted to an open approach. We observed one graft loss due to renal artery kinking in one recipient after left-sided RLDN. Two right donations needed a saphenous venous patch due to a short right renal vein (<2 cm). Overall, intraoperative and postoperative complications were comparable between the two donor groups. CONCLUSION: Right-sided RLDN provides comparable perioperative and postoperative results to those of left-sided RLDN. Our results demonstrated that groups with significant experience in RLDN can perform right living donor nephrectomy safely and efficiently with minimal invasiveness.

Retroperitoneoscopic pyeloplasty for ureteropelvic junction obstruction.

BACKGROUND AND PURPOSE: Retroperitoneoscopy is an established procedure for renal surgery. We evaluated our results with retroperitoneoscopic pyeloplasty for ureteropelvic junction (UPJ) obstruction. PATIENTS AND METHODS: In 14 female and 10 male patients, a retroperitoneoscopic pyeloplasty was performed (13 right/11 left). Four patients had previously had an endopyelotomy. The operation was performed using standard retroperitoneoscopic technique with the patient in a flank position. After preparation of the ureter and renal pelvis, the UPJ was resected in 22 patients in an Anderson-Hynes pyeloplasty. Twenty of these patients had a crossing vessel. The other two patients, who had small renal pelves, were operated on with a Fenger pyeloplasty. In all patients a 7F double-J stent was placed. RESULTS: The mean operative time was 189 minutes (range 70-360 minutes), and the average blood loss was 110 mL (range 50-400 mL). There were no intraoperative complications, although one patient with adhesions and scarring after previous endopyelotomy had to be converted to open surgery. The transurethral catheter was left for 7 days in the first 10 cases and for 4 days in the 14 subsequent patients. The hospitalization time was 9.7 and 7.5 days, respectively. The only postoperative complication was a urinoma, which was punctured. The double-J catheter was removed after an average of 4.6 weeks (range 4-8 weeks). Intravenous urography 6 weeks later showed no obstruction. The mean follow-up time was 11.5 months (range 1-24 months) with no signs of obstruction on ultrasonography. CONCLUSIONS: Retroperitoneoscopic pyeloplasty for UPJ obstruction is a safe and effective procedure. Our short-term results are similar to those of open pyeloplasty with the advantage of a minimally invasive approach.

Curative surgery for solitary adrenal metastasis of pT1 G3 transitional cell carcinoma of the bladder.

A preoperative computed tomography scan in a patient undergoing radical cystectomy for pT1N0 grade 3 transitional cell carcinoma revealed a tumor in the adrenal gland. Biopsy was negative, but 2 years later computed tomography showed progression, and adrenalectomy was performed, revealing transitional cell carcinoma. Four years after cystectomy, the patient had no evidence of other metastases. We discuss surgery for solitary metastasis of transitional cell carcinoma as a curative treatment option.

Retroperitoneoscopic nephropexy for symptomatic nephroptosis using a modified three-point fixation technique.

INTRODUCTION: Laparoscopy has been reported as a minimally invasive approach for performing nephropexy in patients with nephroptosis. We evaluated our results after retroperitoneoscopic nephropexy using a modified three-point fixation technique. TECHNICAL CONSIDERATIONS: Twelve women presenting with flank pain and radiologically documented nephroptosis underwent retroperitoneoscopic nephropexy. After complete dissection of the perirenal fat from the kidney, three nonabsorbable (Ethibond-0) sutures were placed on the posterior renal capsule between the upper pole, middle part, and lower pole of the kidney and the psoas muscle. The average operative time was 91 minutes (range 50 to 180), and the mean estimated blood loss was less than 50 mL in all patients. Postoperative urography revealed complete resolution of nephroptosis in all cases. On a comparative pain analog score patients had 84% improvement (range 0% to 100%). Nine patients had complete resolution of their pain, and two had improvement of 70% to 80%. One patient did not have any improvement. The mean follow-up time was 3.4 years (range 0.5 to 5.5). CONCLUSIONS: Retroperitoneosopic nephropexy with a modified three-point fixation technique of the upper posterior pole, middle part, and lower pole of the kidney to the psoas muscle is a rapid and effective minimally invasive procedure for treating symptomatic nephroptosis with excellent intermediate-term results.

First case of lymphangioma of the bladder in an adult.

Lymphangioma is a congenital malformation consisting of a developmental or primary defect of the lymphatic channels. We report the first case of lymphangioma of the bladder in an adult and review the literature. In our case a 49-year-old man presented with irritative voiding symptoms, cystoscopy showed a non-papillary tumor between the two orifices within the trigone, and transurethral resection was performed. Three months after operation the irritative voiding symptoms had improved and cystoscopy showed no residual tumor.
