Comparison of Topical Anesthetics and Lubricants Prior to Urethral Catheterization in Males: A Randomized Controlled Trial

ACADEMIC EMERGENCY MEDICINE, Issue 6 2004
John Siderias DO
Abstract Although male urethral catheterization in the emergency department (ED) is both common and painful, few studies have evaluated the use of topical anesthesia prior to catheterization. Objectives: To determine whether pretreatment of the urethra with topical lidocaine reduces the pain associated with urethral catheterization. Methods:This was a prospective, double-blind, randomized clinical trial of 36 alert, cooperative male adult patients requiring urethral catheterization, without allergies to the study medications or contraindications to their use, from a suburban university-based ED. Patients in the experimental group had topical lidocaine 2% gel injected in their urethras, whereas control patients received intraurethral lubrication only. Standardized catheterization with a no. 16 Foley was performed followed by pain assessment. The primary outcome measured was pain of catheterization on a 100-mm visual analog scale. Other outcomes included ease of insertion and procedural bleeding. Results: The authors evaluated 36 patients evenly distributed between study groups. Mean age was 62 years (range 22,85). Compared with controls, patients pretreated with lidocaine experienced significantly less pain of catheterization (38 ± 28 mm vs. 58 ± 30 mm; mean difference 20 mm; 95% confidence interval [95% CI] = 0.4 to 32; p = 0.04) and less pain of injection (23 ± 17 mm vs. 40 ± 25 mm; mean difference 17 mm; 95% CI = 3 to 32 mm; p = 0.02). There were no differences in the number of attempts and incidence of adverse events between the groups. Conclusions: Use of topical lidocaine gel reduces the pain associated with male urethral catheterization in comparison with topical lubricants only. [source]

Catheter-Free 120W lithium triborate (LBO) laser photoselective vaporization prostatectomy (PVP) for benign prostatic hyperplasia (BPH)

Abstract Introduction and Objective We evaluate the safety and efficacy of catheter-free LBO laser PVP for the treatment of lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). Methods We prospectively evaluated our initial LBO laser PVP experience and the need for urethral catheterization. Results Seventy consecutive patients were identified. 49 (70%) were discharged without (C,) and 21 (30%) were discharged with (C+) a urethral catheter. There were no significant differences in pre-operative parameters, including age (C,: 65±10 vs. C+: 69±9 years), AUASS (C,: 22±6 vs. C+: 21±6), Qmax (C,: 10±4 vs. C+: 8±3 ml/second), PVR (C,: 62±105 vs. C+: 57±82 ml) and prostate volume (C,: 65±35 vs. C+: 86±53 ml). There were no significant differences in laser time and energy usage. AUASS, Qmax and PVR values showed significant improvement within each group (P<0.05), but there were no significant differences between the two groups. All were outpatient procedures. 2/70 (2.9%) patients required catheter reinsertion in C+. The overall incidence of adverse events was low and did not differ between the two groups. Conclusions Our experience suggests that catheter-free LBO laser PVP is safe and effective for the treatment of LUTS secondary to BPH. Lesers Surg. Med. 40:529,534, 2008. © 2008 Wiley-Liss, Inc.

Expanded PTFE bladder neck slings for incontinence in children: the long-term outcome

BJU INTERNATIONAL, Issue 1 2004
P. Godbole
OBJECTIVE To assess the long-term outcome of circumferential expanded PTFE (Gore-texTM, WL Gore Associates, Scotland) bladder neck slings for achieving urethral continence in children with a neuropathic bladder. PATIENTS AND METHODS The records were reviewed of 19 children undergoing bladder reconstruction (most with a neuropathic bladder) who had a Gore-tex sling placed circumferentially at the bladder neck, over a 5-year period. Of these, seven had spina bifida; two each spinal dysraphism, surgery for anorectal anomalies and an idiopathic neuropathic bladder; five who developed a neuropathic bladder from other causes, and one born with bladder exstrophy. All children had an uncompliant bladder with a low urethral leak-point pressure on preoperative urodynamics. In all children conventional clean intermittent catheterization and pharmacotherapy had failed. Four had had previous augmentation surgery while 15 had concomitant bladder augmentation and formation of a Mitrofanoff stoma. The main outcome measure was achieving dryness. The original intention of the procedure was also to maintain urethral catheterization. RESULTS Full details of the follow-up were available in 17 patients. Despite initial good short-term results, at a median follow up of 7 years, in 14 patients the sling had to be removed because of erosion, often with transient urethral leakage before the bladder neck subsequently closed. A bladder calculus was associated with each case of erosion except one. CONCLUSION Although in the short term this technique had favourable results, it was not a useful technique in the long term.
