Propensity score-matched analysis comparing perioperative, functional, and safety outcomes between thulium fiber laser and bipolar enucleation of the prostate performed by a single surgeon with two years of follow-up.

Purpose: To compare perioperative, functional, and safety outcomes between thulium fiber laser enucleation of the prostate (ThuFLEP) and bipolar enucleation of the prostate performed by a single surgeon with use of propensity score (PS)-matched analysis.

Materials And Methods: Data were from 675 patients, 422 of whom underwent ThuFLEP and bipolar enucleation by a single highly experienced surgeon. ThuFLEP was performed with Fiberlase U1 (IRE Polus Ltd.

[Mini-PCNL, micro-PCNL or RIRS: comparative efficacy and safety in renal stones up to 2 cm].

Introduction: One of the main trends in the evolution of endoscopic treatment of urolithiasis is the miniaturization of instruments. This is obvious in the development of minimally invasive percutaneous nephro-lithotomy (PCNL) and retrograde intrarenal surgery (RIRS). However, there are few studies comparing the efficiency and safety of these methods.

[The comparative characteristic of methods of flow cytofluorometry and optical microscopy in qualitative study of urine elements.].

The comparative study was carried out concerning methods of flow cytofluorometry and optical microscopy in analysis of urine elements with the purpose of establishing the necessity of verification by physician the results of clinical diagnostic laboratory obtained by the analyzer. The final data concerning comparison of results obtained by two methodologies for various groups of pathology. The participation of physician in validation of results can be avoided in the groups with normal and exceeding standard values of content of corpuscular elements of urine.

[A comparative analysis of antireflux and direct methods of ureteral implantation in intestinal continent urinary derivation].

Intestinal continent urinary derivation was made from 1997 to 2006 in three groups of patients. The following kinds of derivation were performed: ureterosygmostomy according to Maintz-Pouch and Abol-Enein modification (group 1, n=32); heterotopic replacement of the urinary bladder in various modifications (group 2, 50 patients); orthotopic replacement according to Hautmann, Studer, Abol-Enein, sygmocystoplasty, n=51). In group 1 ureterosygmoanastomosis was created only by antireflux methods: Goodwin and Hohenfellner submucous technique and Abol-Enein extramural implantation.

[Heterotopic urine derivation in females with urinary bladder extrophy].

Fifteen females aged from 17 to 31 years with bladder extrophy (the condition after ureterosygmostomy) have undergone heterotopic urine derivation with creation of a cutaneous urine-retention catheter mechanism. Surgery was indicated in progressive decline of renal function in the presence of renal reflux, total urine incontinence in the failure of pelvic floor muscles and rectal sphyncter apparatus. Creation of cutaneous urine-retention catheter mechanism was made by the following techniques: heterotopic plastic repair from the ileocecal angle by Mainz pouch I (11 patients, 73.
