conclusions the severity of pathological changes in renal parenchyma, due to upjo, is a good predictor of renal function recoverability, after pyeloplasty. the orus, with drf > 35%, usually have normal (grade i) renal biopsy and might be expected to present better functional recoverability after pyeloplasty. results this study showed a linear relationship between the severity of histological ch...

PURPOSE To evaluate changes in differential renal function (DRF), as a functional outcome, in children who underwent redo pyeloplasty for management of failed pyeloplasty and to examine the factors that affect functional outcomes. MATERIALS AND METHODS Between January 2002 and November 2010, a total of 18 patients who underwent redo pyeloplasty for persistent ureteropelvic junction obstructio...

BACKGROUND AND PURPOSE Minimally invasive pyeloplasty is an effective treatment for patients with ureteropelvic junction obstruction that offers quicker convalescence than open pyeloplasty. Technical challenges, however, may have limited its dissemination. We examined population trends and determinants of surgical options for ureteropelvic junction obstruction. PATIENTS AND METHODS Using the ...

Pyeloplasty remains the gold standard therapy in the treatment of ureteropelvic junction obstruction. Laparoscopic pyeloplasty provides a minimally invasive alternative to open pyeloplasty without compromise of treatment success or durability. Presented is the surgical technique of laparoscopic pyeloplasty.

PURPOSE Laparoscopic pyeloplasty has been associated with long operative times. This study proposed to evaluate the feasibility of two different laparoscopic techniques for the performance of pyeloplasty repair of secondary ureteropelvic junction (UPJ) obstruction. MATERIALS AND METHODS Sixteen female Yucatan minipigs underwent general anesthesia for cystoscopy, retrograde pyelography, urine ...

Joseph Lister was the pioneer of antiseptic surgery (Fig. 1). In the late 19th century, postoperative sepsis accounted for the death of almost half of the patients undergoing major surgery. Building on the work of Pasteur, Lister promoted the use of carbolic acid when operating. Antiseptic surgery became the norm and earned him the title ‘Father of Modern Surgery’. Just as antiseptic surgery re...

OBJECTIVE Laparoscopy in combination with nephroscopy is rarely used for the treatment of complex urinary stones or anatomical abnormalities with difficult access stones. During the nephroscopy, in an opened renal pelvis, large amounts of fluid leaks and collects in the peritoneal cavity and can be a drawback. In these cases, the nephroscopy with use of carbon dioxide (CO2) can be an alternativ...

AIM To assess if calibration of the ureteropelvic junction (UPJ) using a high-pressure balloon inflated at the UPJ level in patients with suspected crossing vessels (CV) could differentiate between intrinsic and extrinsic stenosis prior to laparoscopic vascular hitch (VH). MATERIALS AND METHODS We reviewed patients with UPJO diagnosed at childhood or adolescence without previous evidence of a...

We present the experience of the Minimally Invasive Surgery Centre (MISC) in the development of a modular training model in laparoscopic surgery. The experience analysis includes the description of the training objectives, the learning process of simple and advance laparoscopic urologic techniques, as well as some current and future considerations before applying the laparoscopic techniques. Th...

Aim. Ureteropelvic junction obstruction (UPJO) is rarely associated with a duplex collecting system. We review this unusual anomaly in terms of presentation, diagnostic evaluation, and surgical management. Method. We retrospectively reviewed the medical records of patients diagnosed with a duplex system with UPJO. Result. Sixteen patients (6 girls, 10 boys) with 18 moieties were treated surgica...
