Editor's comment

Abstract

International Braz J UrolThe May -June 2006 issue of the International Braz J Urol presents interesting contributions from different countries, and as usual, the Editor's Comment highlights some important papers. Doctor Daneshgari, from the Cleveland Clinic Foundation, Cleveland, Ohio, USA, recognized expert in the field, presents on page 262 a thorough review on current applications of neuromodulation of the lower urinary tract in female urology. Currently neuromodulation consist of the use of sacral nerve stimulation (SNS) and injectable therapies. In this review, the author discuss the background and development of SNS, its current indications, methods of patient selection and review the results of the recent published literature on SNS. The author also discusses some of the newer developments in SNS such as Bion device and the future direction in integration of SNS in female urology. Doctor Camargo and colleagues, from University of California San Francisco, California, USA, discuss on page 273 the effect of kidney morcellation on operative time, incision complications, and postoperative analgesia after laparoscopic nephrectomy. After comparing the outcomes between kidney morcellation and 2 types of open specimen extraction incisions in 153 consecutive patients who underwent laparoscopic nephrectomy. A hundred and seven patients underwent specimen morcellation and 46 underwent intact specimen removal. Operative time, postoperative analgesia requirements, and incisional complications were evaluated. The authors concluded that morcellation does not extend operative time, and is associated with significantly less postoperative pain compared to intact specimen retrieval overall, although this is not statistically significant if a remote, muscle-splitting incision is made. Also, the authors found that morcellation markedly reduces the risk of incisional-related complications.Doctor Kupeli and co-workers, from Gazi University School of Medicine, Ankara, Turkey, analyzed on page 287 the impact of pelvicaliceal anatomical variation between the stone-bearing and normal contralateral kidney on stone formation in adult patients with lower caliceal stones. The authors concluded that pelvicaliceal volume but not lower caliceal properties seem to be a risk factor for stone formation in lower calyx.
