1/2. Treatment of ureterocele on duplex ureter: upper pole nephrectomy by retroperitoneoscopy in children based on a series of 24 cases.

    OBJECTIVE: The objective of this study is to present the results of a preliminary series of 24 upper pole nephrectomies performed by retroperitoneoscopy in children between 1995 and 2000. MATERIAL AND methods: The patient was placed in the lateral supine position and 3-4 trocars were inserted. Parenchymal section was performed by ultrasound or unipolar scalpel. This series of 24 children consisted of 15 girls and 9 boys with a mean age of 22 months. RESULT: Three cases (12.5%) required open conversion. Nine intraoperative complications (37%) were observed and repaired intraoperatively. Five postoperative complications (20%) consisted of residual perirenal collections, requiring drainage under anaesthesia in only one case. The mean operating time was 2 hours 40 minutes. The mean hospital stay was 3.4 days. The mean follow-up was 32 months. No cases of secondary atrophy of the lower pole were observed. CONCLUSION: overall, these preliminary results are comparable to those of conventional open surgery. The advantage of this method is a reduction of skin and musculo-aponeurotic scars.

2/2. Endoscopic management of milk of calcium-filled ureterocele stump.

    A 38-year-old woman with a duplicated right collecting system and a history of right upper-pole heminephrectomy was referred for persistent dysuria and right lower-quadrant abdominal discomfort. Imaging identified a remnant ureter and a ureterocele filled with what appeared to be a large homogenous stone. At cystoscopy, the ureterocele was incised with a holmium:YAG laser, releasing a large quantity of white milky fluid (milk of calcium). There was no evidence of any solid material. Endoscopic evaluation should be the first step in patients with stones in a ureteral stump because milk of calcium may be the etiology of what appears to be a large stone burden in an obstructed system.
