Does Time and Size Matter in Retrograde Intrarenal Surgery? Results Analysis Using a Low-Pressure Technique.

Purpose: Kidney stone disease affects 5% of the population and is associated with non-negligible morbidity. Retrograde intrarenal surgery and percutaneous nephrolithotomy are the treatments of choice. We analyzed the results from our patients who underwent retrograde intrarenal surgery at controlled pressure.

Laparoscopic and open stone surgery.

Introduction: Due to the increasing spread and technical enhancement of endourological methods, open surgery for renal and ureteral calculi almost disappeared.

Materials And Methods: Based on an actual review of literature, we describe indications, technique and clinical importance of the open and laparoscopic management of urolithiasis.

Results: In Europe and Northern America, the surgical therapy of urolithiasis only plays a role in cases of very large or hard stones, after failure of shock wave lithotripsy, percutaneous nephrolithotripsy or ureteroscopic stone removal and in cases of abnormal renal anatomy.

The Clavien classification system to optimize the documentation of PCNL morbidity.

High success rates exceeding 90% are reported with percutaneous nephrolithotomy (PNL) and modifications have further decreased the morbidity while maintaining efficacy. However, complications after or during PNL may occur with an overall complication rate of up to 83%. Although results from several large series on PNL from outstanding centers are reported in the literature, there is still no consensus on how to define complications and stratify them by severity.

[Development of bladder stone following a tension-free vaginal tape procedure: a case report].

The bladder stone formation due to intravesical mesh erosion of tension-free vaginal tape (TVT) is an infrequent complication. We report a case of 73 years old woman, treated in two occasions by means of the positioning of a TVT with the intention of treating its urinary incontinence. The symptoms, of a year of evolution, was characterized by disuria, pelvic pain, diarrea and constitutional syndrome.

[Prostatic lymphoma and review of the literature].
