Corporal plication for penile curvature caused by Peyronie's disease: the patients' perspective.

OBJECTIVE: To determine the acceptability by patients of corporal plication for Peyronie's disease. PATIENTS AND METHODS: A postal questionnaire was sent to 69 patients who had undergone corporal plication for Peyronie's disease between 1992 and 1999, to ascertain the subjective outcome and acceptance by the patients and their sexual partners of the results of the procedure. Of the 65 patients who were still alive, 44 (68%) returned the questionnaire. RESULTS: The mean (range) follow-up was 4.1 (0.5-7.25) years and the mean age of the patients 54.6 (32-80) years. Of the 44 patients responding, 24 (55%) were sexually active; after surgery, 16 (36%) had significant impairment of erections, seven (16%) continued to have significant penile discomfort and 15 (34%) could feel nodules at the suture site. Twenty-five (57%) patients reported a mild and six (14%) a severe persistent penile deformity; 40 (90%) reported having a shorter penis, of whom 22 (55%) thought it significant. Overall, 14 (32%) reported 'numbness' of the glans penis. Only 23 (52%) of the patients would recommend the surgery, with 25 (57%) reporting a deterioration in their overall quality of life. Of the partners of the evaluable patients, 38 (86%) responded, and a significant deterioration in sexual performance was reported by 19 (35%). CONCLUSIONS: Overall, the long-term results of corporal plication appear to be disappointing. These poor results could be related to a current lack of understanding of the natural history and progression of the disease, to case selection, or to the surgery. We intend to use these results to counsel our patients before such surgery and inform them of the possible outcome in the long term.

Is it necessary to perform urine cytology in screening patients with haematuria?

UNLABELLED: All patients with gross haematuria and those older than 50 years with microscopic haematuria need investigations to rule out the presence of a urological malignancy. OBJECTIVE: To study the role of urine cytology in the evaluation of patients with haematuria. METHODS: Two hundred and eighty-five patients were evaluated. All patients underwent evaluation including urine cytology, flexible cystoscopy, ultrasonography and/or IVU. RESULTS: The mean age of the patients was 62.4 years. Sixty-five percent had gross and 35% microscopic haematuria. Fifty-five tumours were discovered (19.2%); of these 48 were transitional cell carcinomas, 3 renal cell carcinomas and 3 carcinomas of the prostate. Thirty-seven urinary cytologies were abnormal. The overall sensitivity of urinary cytology was 42.4% and specificity 94.3%. Of 18 patients with positive cytology, all were found to have transitional cell carcinomas on cystoscopy or imaging. Of 19 patients with suspicious cytologies, only 6 were found to have tumours. The remaining 13 patients had no evidence of tumour on combined upper tract imaging (IVU and ultrasound) or on rigid cystoscopy and bladder biopsy. Whilst all the other investigation modalities contributed to diagnoses (and/or exclusion of tumours), no additional tumours were discovered solely by urinary cytology. A moderate cost saving could be made without compromising diagnostic accuracy. CONCLUSION: Our study suggests that performing routine urine cytology is not relevant in the investigation of patients with haematuria, its role is at best supportive.

Assessment of voiding outcome, sexual function and quality of life two years following KTP/YAG hybrid laser prostatectomy.

OBJECTIVE: To assess the long-term outcome of patients undergoing KTP/YAG hybrid laser treatment for bladder outlet obstruction due to benign prostatic enlargement, in terms of symptomatic relief, complications, sexual function, patient satisfaction and acceptance of procedure. PATIENTS AND METHODS: The study recruited 148 patients prospectively. The hybrid laser treatment involved performing an initial bladder neck incision using KTP laser at 34 W followed by 4/6 point coagulation using NdYAG laser at 60 W. Patients were followed up till 2 years and assessed using uroflowmetry, International Prostate Symptom Score (IPSS), Patient Satisfaction Score (PSS), BPH impact index (BII) and the Danish Prostate Symptom Score (DAN-PSS) sexual function questionnaire. RESULTS: 137 patients were followed up for 2 years. There was a significant improvement in the maximum flow rate, IPSS and Quality of Life Scale (QLS). The mean BII (2.9) and the mean PSS (1.9) were low suggesting overall satisfaction with the procedure. The complications included urethral stricture (0.73%), bladder neck obstruction (2.15%) and retreatment (3.6%). 79.4% had a significant decrease in the ejaculate and 32.8% had a significant change in the strength of erections. On comparing the two groups (sexual function affected vs. not affected), the age, BII, IPSS and PSS were significantly higher (p < 0.05) in the group of patients that were affected. CONCLUSIONS: Following KTP/YAG hybrid laser prostatectomy the outcome for voiding is good and durable for up to 2 years. The patient satisfaction level following the procedure is high and the procedure well accepted. However, significant interference with sexual function occurs, which appears to be occurring in tandem with a poor voiding outcome.

Semen analysis after vasectomy: when and how many?

OBJECTIVE: To assess patient compliance for semen analysis after vasectomy, and to determine the timing and number of semen analyses required to confirm sterility. PATIENTS AND METHODS: The study included 1321 men who underwent vasectomy between October 1995 and June 1998. They were followed up in two groups; in group 1 (one-test method) 961 consecutive patients were asked to provide a semen sample for analysis 4 months after vasectomy. Sterility was defined as the absence of sperm in one sample. If sperm were present in the sample, the test was repeated at monthly intervals until there were no sperm. In group 2 (two-test method) 360 consecutive patients were advised to provide semen samples 3 and 4 months after vasectomy. The absence of sperm in two consecutive samples was defined as the criterion to declare the man azoospermic. The presence of sperm in one sample required further samples every month until two consecutive azoospermic samples were produced. RESULTS: In group 1, 810 patients provided semen samples, of which 783 (97%) had no sperm and the men were thus declared azoospermic. The remaining 27 (3%) samples contained sperm; six men withdrew from follow-up at various times but 21 patients produced a negative sample at some time within 7 months and were declared azoospermic. At the end of the follow-up, 804 (84%) patients had been declared azoospermic. In group 2, 294 (82%) patients provided a semen sample after 3 months but only 259 (72%) did so after 4 months. Of the patients providing the first sample, 287 (98%) were azoospermic, and after the second 252 (97%) were azoospermic. At the end of the follow-up 255 (71%) patients were declared azoospermic. There was no reported paternity in any of the men. CONCLUSION: These results suggest that compliance was better in group 1; when the patients in group 2 were asked to provide a second sample the compliance decreased significantly. The percentage of patients producing an azoospermic sample was similar for semen provided after 3 and 4 months. Thus, provided that the patient is adequately warned about the risk of failure of the vasectomy at any time during his life, a single semen analysis after 3 months is sufficient grounds for discontinuing other contraceptive precautions.
