Objective: To assess prospectively the results of percutaneous sclerotherapy with povidone-iodine of symptomatic renal cysts in adults.
Methods: Fifty two patients were included in this study from august 2004 to november 2006. The operative indication was: pain (41 cases), urinary tract compression (8 cases), and very large cyst (3 cases). The preoperative assessment (site and dimensions of the cyst) always included ultrasonography. CT scan, for morphological assessment, was performed in 39 cases.
Results: The mean age of patients was 63 years (47-75 years). The mean diameter was 76 mm. The cysts were punctured in all the cases directly under local anaesthesia and guided by sonography. The procedure was very well tolerated in every case, with external drainage for 72 hours. Clinical regression was complete in 48 cases (92%), with total ultrasonographic disappearing of the cysts in 31 cases (60%) with a mean follow-up of 14 months (3-29 months).
Conclusion: Percutaneous sclerotherapy with povidone-iodine is a safe, effective and reproducible treatment of symptomatic renal cysts in adults.

This case report presents a rare occurrence of Sarcina ventriculi in a 15-year-old male patient with a clinical history of renal failure due to chronic rejection status post kidney transplantation, with persistent symptoms of diarrhea, nausea, vomiting, and fatigue. Despite exhibiting normal gastrointestinal mucosa upon endoscopy, biopsy analysis revealed chronic gastritis accompanied by the presence of Sarcina ventriculi in a tetrad arrangement across the stomach, duodenum, and distal esophagus. Interestingly, immunohistochemistry (IHC) staining targeting the Helicobacter pylori organism (H.

BACKGROUND Arterial hypertension in pediatric patients often presents complex diagnostic and therapeutic challenges. The diagnosis of hypertension in children is based on different guidelines than in adults, with arterial hypertension in children defined as systolic and/or diastolic blood pressure values at or above the 95th percentile for age, sex, and height. Unlike adult populations, it is predominantly secondary in etiology, with conditions such as renovascular hypertension as common causes.

Background: The American Urologic Association (AUA) and the European Association of Urology (EAU) guidelines endorse percutaneous nephrolithotomy (PCNL) for symptomatic stones larger than 20 mm despite significant risks such as bleeding and urosepsis. Robotic pyelolithotomy (RPL) is emerging as an appealing alternative to PCNL, particularly for patients with anatomical variations like pelvic or horseshoe kidneys, malrotation, previous unsuccessful PCNL, and congenital renal anomalies such as ureteropelvic junction obstruction (UPJO).
Methods: A retrospective observational study was conducted involving patients from Miulli Hospital and A.

To assess the effectiveness and safety of Sacubitril/Valsartan in reducing blood pressure in individuals with non-dialysis-dependent chronic kidney disease (NDD-CKD) Stage 3-5 complicated by hypertension. This study was a multicenter retrospective analysis conducted from March 1, 2022 to March 31, 2024, involving adult patients with NDD-CKD Stage 3-5 and hypertension, who received Sacubitril/Valsartan either as a monotherapy or in addition to current antihypertensive treatments that were insufficient. The main outcomes measured were blood pressure control, changes in blood pressure and laboratory parameters within 8 weeks post-treatment initiation, and incidence of adverse events.

Introduction: There is equipoise among pediatric urologists regarding endoscopic versus surgical intervention for symptomatic Grade 4-5 Vesicoureteric Reflux (VUR), particularly in infancy. Our aim was to assess outcomes of first-line endoscopic treatment in all cases of symptomatic Grade 4-5 VUR and we hypothesised that using endoscopic Dx/HA as first line management for primary VUR would obviate the need for ureteric reimplantation in the majority of cases.
Methods: Retrospective single-surgeon analysis of consecutive patients with primary Grade 4-5 VUR over 15 years.
