Arterio-Ureteral Fistula: A Rare Elusive Cause of Significant Hematuria.

Arterioureteral fistula (AUF) is a direct communication between the ureter and an artery and is a rare cause of catastrophic, life-threatening haematuria. Fistulation may occur between the ureter and the abdominal aorta, common iliac, external and internal iliac, and inferior mesenteric arteries, and is typically observed in patients with a prior history of pelvic radiotherapy, oncological pelvic surgeries, aortoiliac vascular procedures, and pelvic exenteration. There is also an increased frequency of cases amongst patients who have undergone urological diversion surgeries and in those with chronic indwelling ureteric stents requiring repeated exchange.

Major Urological Cancer Surgery for Patients is Safe and Surgical Training Should Be Encouraged During the COVID-19 Pandemic: A Multicentre Analysis of 30-day Outcomes.

Unlabelled: COVID-19 has resulted in the deferral of major surgery for genitourinary (GU) cancers with the exception of cancers with a high risk of progression. We report outcomes for major GU cancer operations, namely radical prostatectomy (RP), radical cystectomy (RC), radical nephrectomy (RN), partial nephrectomy (PN), and nephroureterectomy performed at 13 major GU cancer centres across the UK between March 1 and May 5, 2020. A total of 598 such operations were performed.

An objective scoring system for laparoscopic nephrectomy.

Background And Purpose: The current first-line recommended modality for nephrectomy is by the laparoscopic approach. This is one of the most frequent laparoscopic interventions conducted in urology. From a skills acquisition and delivery perspective in minimally invasive urologic surgery, there is a paucity of objective scoring systems for advanced laparoscopic urologic procedures.

An electrified catheter to resist encrustation by Proteus mirabilis biofilm.

Purpose: We investigated the effect of iontophoresis produced by passing an electric current through silver electrodes attached to catheters on catheter encrustation by crystalline Proteus mirabilis biofilm.

Materials And Methods: Four glass bladder models were catheterized with 16Fr silicone catheters, of which 3 had 0.25 mm silver wires running through and beside the lumen.

Caecocystoplasty for intractable interstitial cystitis: long-term results.

Objective: To evaluate the role of orthotopic substitution caecocystoplasty in intractable interstitial cystitis refractory to conservative measures by looking at long-term follow-up results.

Patients And Methods: We present a retrospective review of eleven patients who underwent a trigone-preserving orthotopic substitution caecocystoplasty for intractable classical interstitial cystitis. All patients received conservative treatment for a mean period of three years.
