A Prospective Observational Study of Foam Sclerotherapy .

An observational prospective study to determine the impact of foam sclerotherapy of large, dominant kidney/liver cysts on quality of life outcomes and kidney/liver cyst volumes at up to 12 months of follow-up in patients with autosomal dominant polycystic kidney disease (ADPKD) and autosomal dominant polycystic liver disease (ADPLD).

AI for Renal Tumors Using Non-Contrast CT

The goal of this observational study is to learn whether the artificial intelligence method can automatically identify and diagnose renal lesions using non-contrast CT or opportunistic screening.

CT KUB in Renal Cysts

1. Primary (main): 1\. Determine the diagnostic accuracy of CT KUB in differentiating between benign and suspicious renal cysts according to the Bosniak classification. 2. Secondary (subsidiary): 1. Assess interobserver agreement in CT KUB interpretation among radiologists with varying levels of expertise. 2. Identify limitations and pitfalls in the use of non-contrast CT KUB for characterizing renal cysts.

Enhanced Recovery After Urologic Surgery

This clinical trial aims to investigate the analgesic efficacy of several perioperative pain management strategies-specifically, epidural analgesia, paravertebral blockade, transversus abdominis plane (TAP) block, intravenous patient-controlled analgesia (PCA), and intrathecal morphine-in patients undergoing a range of urological procedures. These procedures include pediatric circumcision, hydrocelectomy, inguinal hernia repair, renal cyst excision, and transurethral resection of the prostate. The trial will also evaluate the safety profiles of two specific local anesthetics, liposomal bupivacaine and ropivacaine. The primary research question is whether these different analgesic techniques reduce postoperative opioid requirements in patients undergoing urological surgery. A secondary question explores the adverse events associated with the use of liposomal bupivacaine and ropivacaine in this population. Participants will be: Urological surgery patients undergoing one of the aforementioned procedures. These participants will be randomized to receive one of the following pain management modalities: epidural analgesia, paravertebral blockade, TAP block, intravenous PCA, or intrathecal morphine. Patient assessments will be conducted in the post-anesthesia care unit (PACU) and at 2, 6, 12, and 24 hours postoperatively. Outcome measures will include: Numeric Rating Scale (NRS) pain scores, total postoperative analgesic consumption, recovery status, patient satisfaction, and time to return of bowel function.
