Case report: Challenging adult case of erosive coronal sulcus hair thread tourniquet.

Unlabelled: Hair thread tourniquet syndrome has been well described in the literature, with one of the rare presentations including resultant tourniquet of the penis. We describe an unusual case in an adult resulting in erosion of the urethra as well as the reconstructive and social challenges faced in an attempt to preserve the glans.

Radical cystectomy for primary bladder malignancy: a 10 year review.

Background: Radical cystectomy is universally accepted as the definitive treatment for muscle invasive bladder cancer and preventing stage progression in high-risk groups. There are few recent reviews outside of major international centres. We compared our institution's results with published literature.

The infusion trial of micturition.

Objective: To compare three methods for a trial of micturition (TOM) (the midnight removal of the catheter, dawn removal, and a new infusion method) in a randomized prospective study.

Patients And Methods: A total of 118 consecutive patients who had undergone transurethral resection of the prostate (TURP) or bladder neck incision (BNI) underwent TOM by one of the three methods. In the infusion method, the bladder was filled at a fast-drip rate via the catheter from a bag of normal saline connected by an intravenous supply set.

Long-term experience with sclerotherapy for treatment of epididymal cyst and hydrocele.

Background: Symptomatic testicular hydrocele and cyst of the epididymis may be treated with either operation or sclerotherapy.

Methods: The current report presents the experience of a 9 year prospective study using sodium tetradecyl sulphate (STD) sclerotherapy for the treatment of symptomatic hydrocele and/or epididymal cyst.

Results: A total of 102 lesions were treated during the study period, with an initial success rate of 76% which improved to 94% with multiple treatments.

Bilateral epidermoid cysts of the testis.

We present a case of bilateral testicular epidermoid cysts. These lesions were identified in a 22-year-old male who had previously experienced mild testicular trauma. Management consisted of inguinal exploration and wedge resection on one side and transscrotal exploration and excision on the other.

Squamous cell carcinoma of the prostate: a transformation from adenocarcinoma after the use of a luteinizing hormone-releasing hormone agonist and flutamide.

We report a primary squamous cell carcinoma of the prostate that developed in a 57-year-old man, 3 years after treatment with leuprolide and flutamide for Stage D1 adenocarcinoma of the prostate. This is the first case that describes this transformation from adenocarcinoma to squamous cell carcinoma following the use of luteinizing hormone agonists.

Bladder neck preservation following radical prostatectomy: continence and margins.

Between December 1991 and January 1994, 134 patients underwent radical retropubic prostatectomy with bladder neck preservation. Forty-nine patients had a positive margin. Number and location of positive margins were analyzed.

Quality of life 12 months after radical prostatectomy.

Objective: To evaluate the impact of radical prostatectomy (RP) upon quality of life (QOL) in patients with prostate cancer.

Patients And Methods: Seventy-nine patients with prostate cancer were recruited to evaluate the impact of RP upon QOL. The patients comprised two groups: the first group (n = 51) was evaluated 12 months or longer after RP; and the second group (n = 28) was evaluated 1 month prior to RP.

Management of ureteral and renal pelvic recurrence after cystectomy.

Relatively few data are available on UT TCC following cystectomy. In most circumstances nephroureterectomy is the treatment of choice. The risk of bilateral disease is small (2% to 4%); however, in patients with bilateral UT TCC, a solitary kidney, or poor renal function and low-stage, low-grade TCC, renal preservation by local resection and/or topical therapy may be effective.

Primary prostatic lymphoma: a rare prostatic malignancy.

Primary prostatic lymphoma is a very rare condition for which the treatment is ill defined. A case of this condition from Australia is reported and treatment recommendations reviewed.

Uretero-fallopian fistula: an unusual complication of open ureterolithotomy.

We report a case of uretero-fallopian fistula, manifesting as complete urinary incontinence, following open ureterolithotomy for a lower ureteral calculus.

Evolving experience with radical prostatectomy.

Thirty-six radical prostatectomies were performed over an 8-year period; 25 suitable patients (70%) presented with symptoms of bladder outflow obstruction. In 15 cases (44%), initial digital rectal examination was not indicative of malignancy. The primary tumour was understaged pre-operatively in 17 patients (48%).

Continent ileal neobladder urinary diversion: as an alternative to ileal conduit diversion.

Total bladder replacement with an ileal neobladder was performed in five male patients undergoing cystoprostatectomy. The surgical technique and short-term results are reported. Four of these patients exhibited total urinary continence day and night.

Spontaneous knotting of a pigtail ureteric stent in the ureter requiring percutaneous removal.

Insertion of a ureteric stent is a common procedure in urologic practice. Ureteric stenting may be performed for: ureteric obstruction, benign or malignant: to prevent ureteric obstruction from stone fragments after extracorporeal shockwave lithotripsy (ESWL); or to prevent leakage from the upper urinary tract. A case of spontaneous knotting of a ureteric stent in situ is reported.

Corporeal penile plication for correction of erectile penile deformity.

Penile curvature causing functional impairment of sexual intercourse is uncommon but a number of patients are significantly inconvenienced by this condition. Seven patients who had marked erectile deviation were treated with surgical plication for their penile deformity. Mean follow-up was 16 months (range 3-48 months) and no postoperative complications were encountered.

Laser ablation of the prostate in patients with benign prostatic hypertrophy.

Seventeen patients with bladder neck obstruction due to benign prostatic hypertrophy have been treated with the Neodymium: YAG laser. We review our experience since the first patient was treated in September 1990. Using a prototype deflecting gold alloy tip on a quartz laser fibre (Lateralase TM), we ablated obstructing prostatic adenoma and constricting bladder neck tissue.

Calcitonin gene related peptide: vasodilator in ovine hepatic and renal vasculature.

1. Calcitonin gene-related peptide (CGRP) is a product of alternate splicing of the calcitonin gene. It is found in nerves in the vasculature and is known from in vitro studies to be a potent vasodilator.

The cardiovascular effects of human calcitonin gene-related peptide in conscious sheep.

Calcitonin gene-related peptide (CGRP) is localized in nerve fibres in close association with the vasculature. The in vivo effect of human CGRP upon the cardiovascular system was investigated by intravenous infusion of CGRP into seven conscious sheep at doses of 1.5 and 10-pmol/kg per min for 75 min.

Pharmacokinetics and organ-specific metabolism of calcitonin gene-related peptide in sheep.

Calcitonin gene-related peptide (CGRP) is a product of the calcitonin gene with a widespread distribution in neural tissue of the brain, gut and perivascular nerves. Infusion of CGRP produces multiple biological effects, but the physiological significance of these findings will be influenced by the sites and rates of CGRP metabolism. The metabolic clearance rate and half-life of disappearance of human CGRP were estimated in conscious sheep after infusing CGRP at 1 or 5 pmol/kg per min to steady-state conditions.
