Infundibular stenosis is a rare pathological entity that can be congenital or acquired. The condition is the result of the obstruction of the caliceal infundibulum associated with hydrocalycosis, and requires a differential diagnosis with other pathological entities causing segmental dilations of the upper urinary tract: caliceal diverticulum and m...

Prostatic stents were developed as an alternative to conventional surgical therapies. The principle of the method consists of restoring the urinary flow by inserting a tubular structure (stent) that maintains the lumen of the prostatic urethra. Stents were initially introduced as a therapeutic alternative for some cardiovascular diseases; subsequen...

The bladder may represent the site of numerous infectious or noninfectious inflammatory processes. The endoscopic approach of this pathology is limited, in most cases, to diagnostic procedures, but in certain circumstances it may also be used to treat various conditions.

The purpose of endourology is to develop minimally invasive techniques that can equal or surpass the results of classical open surgery. Nephroureterectomy with perimeatic cystectomy, an extensive urologic intervention, naturally determines the search for methods that reduce invasiveness. Endourological techniques have permitted the elimination of o...

The first descriptions of urethro-vesical catheters date back to antiquity, when straws or palm leaves were used for this purpose. In China, Sun Shimiao (581–682 AD) used tubular leaves from green onions through which air was blown to remove the obstacle. In 1036, Avicenna sensed the need for gentle insertion of catheters and created flexible model...

A prospective study was performed aiming to evaluate the surgical efficacy, perioperative safety profile, diagnostic accuracy and medium term results of a multi-modal approach consisting in narrow band imaging (NBI) cystoscopy and bipolar plasma vaporization (BPV) when compared to the standard protocol represented by white light cystoscopy (WLC) an...

A single centre, retrospective trial was performed trying to assess the impact of NBI cystoscopy in cases of non-muscle invasive bladder tumors (NMIBT) by comparison to the standard approach. Our goal was to determine the superiority of the new method in terms of detection rates and subsequent postoperative treatment changes. A total of 320 NMIBT s...

A long term, retrospective study was performed aiming to outline a critical comparison concerning the efficacy, safety and durability of the bipolar plasma vaporization (BPV), standard monopolar transurethral resection (TUR) and "cold-knife" "star" transurethral incision (TUI) in secondary bladder neck sclerosis (BNS) cases. Materials & Methods: Of...

Introduction: Secondary bladder neck sclerosis (BNS) represents a common late complication of prostate surgery, however so far insufficiently assessed in the available literature. More over, the previously attempted and analyzed therapeutic modalities failed to achieve acknowledgement as standard treatment for this particular pathology. Methods: Th...

The standard non-muscle invasive bladder cancer (NMIBC) endoscopic diagnosis suffers from the frequently unsatisfactory white light evaluation accuracy leading to residual lesions being left behind. Monopolar transurethral resection of bladder tumors (TURBT) is marked by a substantial morbidity rate requiring further amelioration. Small size tumors...
