BACKGROUND The Resonance metallic ureteral stent (Cook Medical, Bloomington, Indiana, USA) has been introduced for the management of extrinsic-etiology ureteral obstruction for time periods up to 12 mo. OBJECTIVE The current study aims to determine short- and medium-term effectiveness of the Resonance stent in malignant and benign ureteral obstruction. (More)
Laparoendoscopic single-site surgery (LESS) uses single incisions for the introduction of instruments through a specially designed multi-lumen single port (multi-port) for the performance of several urologic procedures. Literature review regarding the LESS approach took place on May 2009 and the experiences of our institutions were also included. Almost all(More)
Laparoendoscopic single-site surgery (LESS) has emerged in the recent years as an alternative approach to conventional laparoscopic surgery which is accompanied by additional advantages over laparoscopy. In this work we attempt to review the current literature and to investigate the possible combination of LESS to other currently available approaches such(More)
BACKGROUND Laparoendoscopic single-site surgery (LESS) has been developed in an attempt to further reduce the surgical trauma associated with conventional laparoscopy. Partial nephrectomy (PN) represents a challenging indication for LESS. OBJECTIVE To report a large multi-institutional series of LESS-PN and to analyze the predictors of outcomes after(More)
OBJECTIVE The current study investigates the effect of bladder neck (BN) preservation on postoperative continence and positive surgical margins (+SMs). PATIENTS AND METHODS 150 patients (group 1) who underwent BN-sparing endoscopic extraperitoneal radical prostatectomy (EERPE) and 90 patients treated with EERPE and BN resection (group 2) were(More)
We herein review our experience with endoscopic extraperitoneal radical prostatectomy (EERPE) as a first line therapy for localized prostate cancer. A series of 1,300 patients underwent EERPE (“wide excision”, standard nervesparing technique (nsEERPE), or intrafascial nsEERPE). The mean age of the patients was 63.3 years. Preoperative PSA mean value was(More)
PURPOSE To present experience with the percutaneous management of iatrogenic ureteral injuries. PATIENTS AND METHODS Eighteen women and six men with a mean age of 59.3 years (range 33-80 years) received a diagnosis of ureteral injury sustained during gynecologic, urologic, and general surgical procedures. In a total of 25 injured ureters, 12 had(More)
OBJECTIVE To present the experience with the extraperitoneal approach for robotic-assisted simple prostatectomy (RASP) in a technique replicating the vesicocapsular incision technique of open surgery. PATIENTS AND METHODS RASP was performed on patients with a prostate volume of >80 cm(3) with an indication for open enucleation of the prostate.(More)
BACKGROUND AND PURPOSE Ureteral reconstructive surgery necessitates adequate exposure of the ureteral lesion and results in large abdominal incisions. Robot assistance allows the performance of complex ureteral reconstructive surgery through small incisions. The current series includes only cases of Boari flaps performed by robot assistance and attempts to(More)
Laparoendoscopic single-site surgery (LESS) probably represents the next evolutionary step in laparoscopic surgery. Although most urologic procedures are feasible by the LESS approach, significant challenges in terms of intraoperative ergonomics and requirement for laparoscopic skill are present. New, specially designed instruments and ports represent a(More)
