Giant hydronephrosis secondary to ureterocele with duplex system in adults: Report of a case.

Giant hydronephrosis in adults is a rare entity. It is defined as an extensive dilatation of the pyelocaliceal cavities occupying a large part of the abdominal cavity. Giant hydronephrosis is usually due to pelvi-ureteric junction obstruction and is usually diagnosed in children and infants.

[Use of TachoSil in laparoscopic enucleoresection of renal masses smaller than 4 cm: our preliminary experience of 41 cases].

Introduction: In nephron-sparing surgery the use of new and various hemostatic materials has provided a significant support in the control of intraoperative hemostasis of resection bed. Objective of this study is to demonstrate the use of hemostatic material TachoSil in laparoscopic treatment of renal masses <4 cm.

Materials And Methods: 41 patients underwent laparoscopic renal enucleoresection.

[Fluorescence cystoscopy with hexaminolevulinate: our preliminary experience of 184 procedures].

Introduction: Fluorescence cystoscopy (FC) with hexaminolevulinate (HAL) is a recently introduced technique of photodynamic diagnosis (PDD), which aims to improve the accuracy of white light cystoscopy (WLC) in the diagnosis of superficial bladder tumors (NMIBC), and especially of flat urothelial lesions (dysplasia and Ca in situ). We report our experience of a number of cases of WLC and FC in a single moment with HAL in the diagnosis and follow-up of NMIBC.

Materials And Methods: The method was applied to 184 selected patients with a diagnosis or clinical suspicion - instrumental or early recurrence of bladder neoplasia.

[Conservative endoscopic retrograde treatment of upper urinary tract tumors: retrospective analysis of the last 105 cases].

Introduction: Modern flexible ureterorenoscopy allows a retrograde approach to urothelial tumors in the upper urinary tract (UUTT) of small dimensions (<1.5 cm), of low grade and non-invasive. The percutaneous renal approach, although more invasive, provides an alternative treatment in case of larger dimension neoplasia or difficult retrograde access.
