Male Urethral Diverticulum with Stones Presenting as Acute Urinary Retention.

The urethral diverticulum is an outpouching of the urethral wall communicating with its lumen. Acquired male urethral diverticulum is a rare entity and arises secondary to intervention or distal urethral obstruction. Most patients present with lower urinary tract symptoms (LUTS).

Validation of a Bench-Top Training Model for Retrograde Intrarenal Surgery.

Objective: To validate the in-house built Styrofoam box bench-top training model for retrograde intrarenal surgery (RIRS).

Materials And Methods: This study was performed in the setting of a half-day RIRS course. During the course, participants performed RIRS on a locally built bench-top model.

Hounsfield units-a significant predictor of lasering time and energy in the management of upper urinary tract stones using Holmium: Yttrium-Aluminum Garnet lasers.

Purpose: To study the impact of stone density as assessed by Hounsfield units (HU) on total laser energy (TLE) used and total laser time (TLT) spent in complete fragmentation of upper urinary tract stones. In addition, we also studied the impact of stone composition on the laser energy and time required for fragmentation.

Methods: Thirty consecutive patients fulfilling inclusion and exclusion criteria were included in the study.

Metabolic Syndrome: An Indicator of Complicated Gall Stone Disease?

Background Gallstone disease is a common surgical entity worldwide and accounts for a major portion of hospital admissions and surgeries. Metabolic syndrome is diagnosed when three of the following medical conditions are positive: central obesity, high blood pressure, increased fasting glucose levels, low high-density lipoprotein (HDL) levels and high serum triglycerides. Objective To compare the frequency of metabolic syndrome in patients with uncomplicated gallstone disease and complicated gallstone disease.

Stented Pancreatico-duodenectomy: Does it lead to decreased pancreatic fistula rates? A prospective randomized study.

Objective: To compare clinically relevant pancreatic fistula rates in patients with stented versus non-stented pancreatico-jejunostomies.

Methods: The randomised comparative clinical trial was conducted at Civil Hospital, Karachi, from September 2009 to August 2015, and comprised patients presenting to the Surgical Unit 4 with a diagnosis of resectable periampullary carcinoma, carcinoma of head of pancreas, duodenal carcinoma involving the second part, and distal cholangiocarcinomas. Pancreatic fistula or leakage was defined as amylase-rich fluid lasting over 5 days, collected from the peripancreatic drains on day 1, 3 and 7 postoperatively, and the rate of clinically relevant fistulas was taken as primary study endpoint.
