Safety and efficacy of synchronous percutaneous nephrostolithotomy and contralateral ureterorenoscopy for bilateral calculi.

Herein we describe the technique and review the medical records of 26 patients who underwent percutaneous nephrostolithotomy (PCNL) and simultaneous contralateral retrograde ureterorenoscopy (URS) for bilateral urolithiasis of discordant sizes at our institution. Preoperative factors, operative time, change in hemoglobin, change in serum creatinine, stone free, and efficacy rates after a single procedure were analyzed retrospectively. The total efficacy rate--defined as residual calculus of 4 mm or less--was 92.

Laparoscopic nephrectomy for the management of renal medullary carcinoma in a child.

Renal medullary carcinoma is a lethal subtype of renal cancer that afflicts patients with sickle-cell hemoglobinopathies. Here we present the case of a 13-year-old boy with renal medullary carcinoma who is the first, to our knowledge, to be managed using a planned laparoscopic radical nephrectomy.

Issue of prostate gland size, laparoscopic radical prostatectomy, and continence revisited.

Objectives: To evaluate the influence of prostate gland size on the perioperative, pathologic, and continence outcomes after laparoscopic radical prostatectomy (LRP).

Methods: 144 LRPs for which 18-month continence data were available were performed by a single surgeon, and were retrospectively reviewed. Patients were divided initially into two groups based on final prostate gland size: group 1 (weight less than 50 g) and group 2 (weight 50 g or more).

Outcome of percutaneous surgery stratified according to body mass index and kidney stone size.

Objective: To stratify outcome and morbidity of percutaneous nephrostolithotomy (PCNL) with regard to body mass index (BMI) and kidney stone burden.

Methods: The charts of 148 patients who underwent PCNL procedures were reviewed retrospectively. Hospital stay, blood loss, maximal temperature during inpatient stay, and stone-free outcomes were evaluated.

Laparoscopic nephrectomy for a nonfunctioning pelvic kidney in preparation for renal transplantation.

Pelvic kidneys pose a problem for any planned surgical intervention given their anomalous blood supply. Although minimally invasive approaches have been described for the management of benign conditions, only a handful of reports have described the use of laparoscopy for removal of ectopic or fused kidneys. We describe the laparoscopic removal of a symptomatic pelvic kidney in a patient before renal transplantation.
