OBJECTIVE To review the long-term outcome of selective renal arterial embolization (SAE) in treating renal angiomyolipomas (AMLs) in both elective and emergency settings. MATERIALS AND METHODS Between October 1988 and September 2008, 27 patients (28 renal units) were treated with SAE, either on an emergency basis for 15 (53.6%) bleeding AMLs or(More)
BACKGROUND AND PURPOSE A novel technique for managing the distal ureter and bladder cuff during laparoscopic nephroureterectomy is introduced. TECHNIQUE The procedure consists of three steps: (1) cystoscopy and PediPort (Tyco) insertion; (2) establishment of pneumovesicum and intramural ureter mobilization; and (3) laparoscopic nephroureterectomy. The use(More)
A case of prostate cancer metastasized to the breast is presented, the latter being prostate-specific antigen (PSA) positive. This is the first of such cases reported in Hong Kong and China in the English literature. As PSA expression also can be found in primary breast cancer, prostatic acid phosphatase staining was employed to confirm the diagnosis. The(More)
UNLABELLED Study Type - Diagnostic (exploratory cohort) Level of Evidence 3b What's known on the subject? and What does the study add? Electronic uroflowmetry reasonably predicts the likelihood of bladder outlet obstruction (BOO) and risk of AUR. This low-cost device, Uflowmeter(™) , allows men to perform uroflowmetry at home with ease and the results are(More)
Colorectal self-expandable metal stents (SEMS) have been used successfully as preoperative bridges to surgery for obstructive left-sided colorectal carcinoma. Endoscopic relief of the obstruction allows for full bowel preparation and accurate preoperative staging. A laparoscopic approach, considered by many to be contraindicated in the presence of(More)
OBJECTIVE To report the recurrence, progression and survival in patients with T1G3 transitional cell carcinoma (TCC) of the urinary bladder treated with sequential intravesical bacillus Calmette-Guérin (BCG) and chemotherapeutic agents (doxorubicin or epirubicin) on long-term follow up. METHODS Between July 1988 and September 1999, all patients in a(More)
PURPOSE Robot-assisted radical cystectomy (RARC) was first introduced in 2003. Although there have been modifications to the surgical techniques over the years, in every published RARC series the surgical robot is invariably docked between the patient's legs. We evaluated the use of a side-docking approach in RARC. PATIENTS AND METHODS Ten RARCs using a(More)
OBJECTIVE To investigate the feasibility of side-docking techniques in robot-assisted urologic pelvic surgery. MATERIALS AND METHODS Six consecutive patients undergoing robot-assisted pelvic surgery participated in the study: 3 undergoing radical cystectomy for muscle-invasive bladder cancer, 1 patient undergoing ureteroneocystostomy for ureteric(More)
AIM To compare bacillus Calmette-Guerin (BCG) with epirubicin in adjuvant therapy of superficial bladder transitional cell carcinoma, with respect to recurrence, progression and survival. Prognostic factors are also evaluated. METHODS Between October 1991 and September 1999, all patients harboring superficial bladder cancers (Ta or T1) with any of the(More)
BACKGROUND A case series of inverted papilloma of the urinary bladder and urethra is presented, together with a review of the literature with respect to multiplicity, recurrence rate and association with transitional cell carcinoma, and a discussion on surveillance of the lesion. METHODS Cases of inverted papilloma of the lower urinary tract in a single(More)
