Clampless LPN represents a feasible and safe procedure, even for tumours with high surgical complexity, in highly experienced laparoscopic centers. When compared to clamped LPN, it results in better preservation of immediate post-operative renal function.

Introduction: The aim of this study was to compare laparoscopic and open partial nephrectomy (PN) for renal tumors of high surgical complexity (PADUA score ⩾10). Methods: We retrospectively evaluated 93 consecutive patients who underwent PN at our department from January 2015 to September 2019. 21 patients underwent open partial nephrectomy (OPN) (Group A) and 72 underwent laparoscopic partial nephrectomy (LPN) (Group B). All OPNs were performed with a retroperitoneal approach, while all LPNs were performed with a transperitoneal approach by a single surgical team. Post-operative complications were classified according to the Clavien-Dindo system. Results: The two groups showed no difference in terms of patients’ demographics as well as tumor characteristics in all variables. Group A was found to be similar to group B in terms of operation time ( p = 0.781), conversion to radical nephrectomy ( p = 0.3485), and positive surgical margins ( p = 0.338) while estimated blood loss ( p = 0.0205), intra-operative ( p = 0.0104), and post-operative ( p = 0.0081) transfusion rates, drainage time ( p = 0.0012), pain score at post-operative day 1 (<0.0001) were significantly lower in Group B. The rate of enucleation and enucleoresection/polar resection was similar ( p = 0.1821) among the groups. Logistic regression analysis indicated that preoperative factors were not independently associated with the surgical approach. There was a statistically significant difference in complication rate (<0.0001) between the two groups even if no significant difference in terms of grade ⩾3 post-operative complications ( p = 0.3382) was detected. Discussion: LPN represents a feasible and safe approach for high complex renal tumors if performed in highly experienced laparoscopic centers. This procedure offers good intraoperative outcomes and a low rate of post-operative complications.
Introduction: Spontaneous rupture of kidney may involve collecting system or parenchyma. Parenchymal rupture usually occurs in patients with renal cell carcinoma, angiomyolipoma, renal cysts, arteriovenous malformation or vascular diseases such as periarteritis nodosa. Collecting system rupture is usually a rare complication of obstructive urolithiasis. We describe the unusual cases of spontaneous kidney rupture in patients with acute urinary obstruction. Case presentation: The case report describes the left parenchymal kidney explosion related to ipsilateral ureteral obstruction caused by a single ureteral stone. The patient reached our emergency department with acute left flank pain and massive haematuria. At the moment of admission, the patient was in stage III hypovolemic shock and had a lower haematocrit (haemoglobin = 4.9 g/dL). Despite blood transfusions, emergency surgical exploration, extrafascial nephrectomy and intensive support care, the patient died twelve hours after surgery. Conclusions: Parenchymal renal rupture can be a life-threatening emergency. Despite its rarity, in the differential diagnosis of acute abdomen, parenchymal renal rupture should always be considered in patients with abdominal pain and an anamnesis or history of urinary stones, pointing out the need of early diagnosis also in benign urological conditions.
<b><i>Introduction:</i></b> To evaluate the efficacy of Bifiprost® + Serenoa Repens 320 mg versus Serenoa Repens 320 mg alone for the prevention of chronic bacterial prostatitis (CBP) due to enterobacteriaceae. <b><i>Methods:</i></b> Between September 2016 and September 2018, 120 patients with CBP at the National Institutes of Health (NIH type II) with recurrent infections due to enterobacteriaceae (<i>Escherichia Coli</i> and <i>Enterococcus faecalis</i>) were enrolled and randomized into 2 groups each to receive Bifiprost® + Serenoa Repens 320 mg (Group A) or Serenoa Repens 320 mg alone (Group B) daily for 24 weeks (after receiving a proper antibiotic treatment with subsequent culture negativization). The primary endpoint was the reduction in the episodes of prostatitis. The secondary endpoint evaluated was the score of the NIH-Chronic Prostatitis Symptom Index (NIH-CPSI). Evaluation was performed at baseline and at 12, 24, and 36 weeks. <b><i>Results:</i></b> The patients of the Group A experienced a significantly larger reduction in the prostatitis episodes than the Group B at 24 and 36 weeks, but they did not experience a significantly larger reduction at 12 weeks. After 12 weeks of treatment, the mean NIH-CPSI score was reduced in both groups compared with baselines, but no significant differences were seen between the Group A and Group B. On the contrary, we observed a significant difference in the mean NIH-CPSI score between the 2 groups at 24 and 36 weeks. <b><i>Conclusion:</i></b> The association of Bifiprost® and Serenoa Repens 320 mg improves the prevention of the episodes of CBP due to enterobacteriaceae and ameliorates prostatitis-related symptoms after 6 months of therapy. The long-term impact on the entero-urinary route was also seen 3 months after the end of the treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
