Retroperitoneal Laparoscopic Nephrectomy for Inflammatory Renal Diseases / 대한비뇨기과학회지

PURPOSE: Retroperitoneal laparoscopic nephrectomy for inflammatory renal conditions remains technically challenging, but can prevent intraperitoneal contamination by inflammatory or pathologic materials and decrease the risk of visceral injury or peritoneal morbidity. We evaluated retroperitoneal laparoscopic nephrectomy in terms of feasibility, safety, and efficacy in inflammatory renal disease. MATERIALS AND METHODS: Between March 2003 and June 2006, retroperitoneal laparoscopic nephrectomy was performed in 39 patients with benign renal disease. Of the 39 patients, 18(group 1) had inflammatory renal diseases with perinephric stranding on CT, which was confirmed as an adhesion during surgery. The remaining 21 patients(group 2) had nonfunctioning kidneys without significant inflammation. Intraoperative and postoperative clinical parameters were analyzed and compared between the 2 groups. RESULTS: Retroperitoneal laparoscopic nephrectomy was successful in all 39 patients without conversion to open surgery. Group 1 included tuberculous pyelonephritic kidney(n=11), xanthogranulomatous pyelonephritis (n=3), pyonephrosis(n=2) and renal abscess(n=2). Group 2 included chronic pyelonephritis(n=12), ureteropelvic junction obstruction(UPJ) stricture(n=6), and cystic disease(n=3). The mean operating time and the mean estimated blood loss were significantly different between the 2 groups(p<0.001). The mean time to oral intake and ambulation, and the mean duration of hospitalization were not different between the 2 groups. There were 1 major and 2 minor complications in group 1 and 2 minor complications in group 2. CONCLUSIONS: Retroperitoneal laparoscopic nephrectomy is a feasible and safe treatment modality in inflammatory renal diseases as well as other benign renal diseases.

Ureteral Endometriosis / 대한비뇨기과학회지

Endometriosis is defined as the presence of functional endometrial tissue in an ectopic site. The incidence of endometriosis is from 10% to 20% for women of reproductive age. From 1% to 2% of woman with endometriosis have urinary tract lesions, of which from 70% to 80% involve the bladder. Yet ureteral endometriosis is very uncommon, and it is noted in only 0.1% to 0.4% of these cases. We report here on one case of ureteral endometriosis.
