Retrograde intrarenal surgery and micro-percutaneous nephrolithotomy for renal lithiasis smaller than 2 CM.

Introduction: Microperc is the upgraded form of percutaneous nephrolithotomy miniaturization. The aim of this study is to compare prospectively microperc and retrograde intrarenal surgery for the treatment of renal stones smaller than 2 cm.

Material And Methods: A comparative prospective study of both techniques was carried out between January 2014 and June 2015.

Influence of barbed suture in laparoscopic radical prostatectomy.

Objectives: To determine the influence of barbed suture in laparoscopic radical prostatectomy.

Methods: A retrospective study of 150 patients who underwent laparoscopic radical prostatectomy was carried out by our department. The patients were divided in two groups according to the kind of suture used during the vesicourethral anastomosis: conventional 3-0 absorbable multifilament running suture (group 1) and bidirectional barbed suture (Quill®) (group 2).

Flexible ureteroscopy for renal stones.

Objectives: The objectives of this prospective study are to present our experience with retrograde intrarenal surgery (RIRS), and to analyze its results and complications.

Material And Methods: 150 patients with renal stones were treated with RIRS. 111 cases showed single stones whilst multiple stones were observed in 39 cases.

Predicting results of daily-practice cystoscopies.

Objective: Our objective was to elaborate a predictive model of bladder cancer, in an unselected clinical population submitted to cystoscopy.

Materials And Methods: We recruited consecutive patients that underwent cystoscopy due to suspicion of bladder cancer or surveillance of a previously diagnosed bladder cancer. Urine cytology and a BTA-stat® (BTA) test were carried out for all patients.

[Retrograde intrarenal surgery (RIRS). Technical complement for cases of acute lithiasis].

Introduction: Washing the renal cavities using minipercutaneous surgery shaft is an ideal technical procedure for retrograde intrarenal surgery (RIRS) when lithiasic fragmentation is significant or if the anatomy of the renal cavities may obstruct the spontaneous elimination of fragments.

Materials And Methods: we performed 37 RIRS on 35 patients with renal lithiasis (14 men, 21 women) with a mean age of 56 (range 33-72) years, divided into two groups in accordance with the size of their kidney stones. Group A, 23 patients with lithiasis <1.
