Despite the modern advancement in endourology, percutaneous nephrostomy play an important role in many urologic conditions, which of the most important is the relief of upper urinary tract in patients with malignancies that interests the ureter or the uretero-vesical junction. The aim of the study is to compare the complications of polyurethane and silicone catheters used for percutaneous nephrostomy in patients with unilateral or bilateral uretero-hydronephrosis secondary to locally advanced abdomino-pelvin malignancies. We have retrospective analyzed 164 patients (p), admitted between January 2013 and December 2016 in Urology Department Sibiu, who benefit from unilateral or bilateral percutaneous nephrostomy for secondary uretero-hydronephrosis with acute renal failure.

Introduction. Sparing kidney tissue is important because studies show that patients who have their entire kidney removed are more likely to suffer from chronic kidney disease after surgery than patients who received a kidney-sparing partial nephrectomy. The aim of study is to show the effectives of Pringle maneuver for clamping renal pedicle in order to minimize warm ischemia during open partial nephrectomy. Material and method. We retrospectively analyzed 34 patients diagnosed with cT1 renal tumors between 2012 and 2016 and underwent open partial nephrectomy in Sibiu Urology Department. During the surgery we perform clamping of renal pedicle with Satinsky clamp or with the Pringle maneuver. We analyzed the flowing parameters: operation time, blood loss, clamping time and serum creatinine before and after the surgery. Results. The mean age of patient with partial nephrectomy was 58.7±14.7 years, with 56.7±12.4 years for Satinsky group and 60.5±11.6 for Pringle group. The average duration for partial nephrectomy was 94.8±19.4 minutes. Average boold loss for all surgeries was 220±30 ml. Conclusion. Pringle maneuver is a safe and effective method with low intra and postoperative complications during open partial nephrectomy, having a good control of the renal pedical with reduced ischemia. Is a feasible method of choice in renal tumour tumor pathology on a single congenital or surgical kidney, mediorenal tumors or near the sinus and multifocal tumors. [ABSTRACT FROM AUTHOR]

Introduction. Partial nephrectomy represent the standard of care for small renal tumor. Laproscopic approach tends to replace open surgery due to similar oncologic results, but with better eastethic outcomes and earlier socio-professional reintegration. Material and methods. Between January 2010 and February 2017, 55 patients (p) underwent partial nephrectomy at our center for clinically localized renal tumor, 21p with LPN by retroperitoneal approach and 34p with OPN. All patients had a normal contralateral kidney. The selection of patients for nephron-sparing surgery was based on preoperative CT scan, location of the tumor, the individual general health status of the patient and individual surgeon preferences. Results. The mean age of patients with partial nephrectomy was 59.6±16.4 years, with 57.9±11.6 years for laparoscopic subgroup and 61.3±12.4 for open surgery. The transfusion rate was 9.52% in LPN group, while in the OPN there was no need for transfusion. The warm ischemia time was higher in the LPN group (21.8±7.2 min) than OPN group (15.7±2.9). The postoperative complication rate is comparable between LPN and OPN (23.81% v.s. 20.58%), but the LPN had higher intraoperative complications. Conclusion. Laparoscopic partial nephrectomy for renal tumors is superior to open surgery by early mobilization of the patient, the low rate of wound complications, short duration of hospitalization, fast socio-professional reintegration of patient, despite the perioperative complication rate that is higher but of low ClavienDindo grade.
