Transurethral En Bloc Resection Versus Standard Resection of Bladder Tumour: A Randomised, Multicentre, Phase 3 Trial.

Background And Objective: Conventionally, standard resection (SR) is performed by resecting the bladder tumour in a piecemeal manner. En bloc resection of the bladder tumour (ERBT) has been proposed as an alternative technique in treating non-muscle-invasive bladder cancer (NMIBC). The objective of this study is to investigate whether ERBT could improve the 1-yr recurrence rate of NMIBC, as compared with SR.

Use of indocyanine green angiography in microsurgical subinguinal varicocelectomy - lessons learned from our initial experience.

Microsurgical subinguinal varicocelectomy (MSV) is generally considered the gold standard nowadays in view of the lower risk of complications and recurrence. To achieve complete ligation of veins while preserving testicular artery (TA) during the procedure remains challenging despite the application of high power optical magnification and micro-Doppler ultrasonography. The use of intraoperative indocyanine green angiography (ICGA) with infrared fluorescence operative micro-scope in MSV potentially lowers the incidence of TA injury and shortens the learning curve of nov-ice surgeons.

Emphysematous pyelonephritis: an 8-year retrospective review across four acute hospitals.

Objective: To retrospectively review our experience of managing patients with emphysematous pyelonephritis (EPN).

Methods: Case notes of patients with EPN were reviewed. The patients' demographic data, clinical presentation, investigation findings, treatment, and outcome were studied.

The destruction of the lower urinary tract by ketamine abuse: a new syndrome?

Objective: To report the clinical spectrum seen in young abusers of street-ketamine (regular recreational abusers of street-ketamine, for its hallucinogenic effects) in Hong Kong, presenting with significant lower urinary tract symptoms (LUTS) but with no evidence of bacterial infection.

Patients And Methods: We retrospectively analysed the clinical presentations, pelvic pain and urgency/frequency scores, video-urodynamic studies, cystoscopy findings, histological features of bladder biopsies and radiological findings of 59 ketamine abusers who were referred to the urology units of Princess Margaret and Tuen Mun Hospital, Hong Kong, from March 2000 to December 2007.

Results: Of the 59 patients, all had moderate to severe LUTS, i.
