OBJECTIVES: To present our experience with hand-assisted laparoscopy (HAL) for larger renal specimens. One of the theoretical benefits of HAL is the ability to manage large renal specimens, which we defined as tumors greater than 7 cm, and tumors in obese patients. METHODS: Between March 1998 and October 2000, 106 HAL radical nephrectomies were performed for enhancing renal masses, for which 95 patients had complete preoperative, intraoperative, and postoperative data. Of the 95 patients, 32 underwent HAL for large tumors (7 cm or greater) and 41 had a body mass index of 31 or greater. The demographic and outcome data of these two groups were compared with 63 patients who underwent HAL for tumors less than 7 cm and 54 patients with a body mass index of less than 31. RESULTS: When comparing cohorts by tumor size, the only statistically significant differences were in convalescence and specimen weight. Patients with lesions 7 cm or greater required 21 days to recover compared with 18 days for patients with lesions less than 7 cm. Obese patients had statistically significantly higher American Society of Anesthesiologists classifications, longer operative times (214 versus 176 minutes), and longer convalescences (21 versus 17.5 days) compared with nonobese patients. The estimated blood loss and conversion rate was not different between the groups. Furthermore, no difference was noted between the groups in the incidence of positive margins, local recurrence, or metastatic recurrence at a mean follow-up of 12.2 months. CONCLUSIONS: HAL provides a safe, reproducible, and minimally invasive technique to remove large renal tumors and renal tumors in the obese

Incontinence in a child with a duplex kidney: case report

Handler, Toby F; Shapiro, Ellen
Persistent incontinence after toilet training in young girls and urinary tract infections or epididymitis in prepubertal boys should raise suspicion of an ectopic ureter. This often occurs in the context of duplication of kidney structures or other parenchymal abnormalities. The presence or absence of reflux affects surgical treatment, which may consist of ureteral reimplantation, ureteroureterostomy, and/or upper pole nephrectomy
