Urethral stricture following endoscopic prostate surgery: a systematic review and meta-analysis of prospective, randomized trials

Flaws in the design, conduct, analysis, and reporting of randomised trials can cause the effect of an intervention to be underestimated or overestimated. The Cochrane Collaboration’s tool for assessing risk of bias aims to make the process clearer and more accurate

To update the complications of transurethral resection of the prostate (TURP), including management and prevention based on technological evolution. Based on a MEDLINE search from 1989 to 2005, the 2003 results of quality management of Baden-Württemberg, and long-term personal experience at three German centers, the incidence of complications after TURP was analyzed for three subsequent periods: early (1979-1994); intermediate (1994-1999); and recent (2000-2005) with recommendations for management and prevention. Technological improvements such as microprocessor-controlled units, better armamentarium such as video TUR, and training helped to reduce perioperative complications (recent vs. early) such as transfusion rate (0.4% vs. 7.1%), TUR syndrome (0.0% vs. 1.1%), clot retention (2% vs. 5%), and urinary tract infection (1.7% vs. 8.2%). Urinary retention (3% vs. 9%) is generally attributed to primary detrusor failure rather than to incomplete resection. Early urge incontinence occurs in up to 30-40% of patients; however, late iatrogenic stress incontinence is rare (<0.5%). Despite an increasing age (55% of patients are older than 70), the associated morbidity of TURP maintained at a low level (<1%) with a mortality rate of 0-0.25%. The major late complications are urethral strictures (2.2-9.8%) and bladder neck contractures (0.3-9.2%). The retreatment rate range is 3-14.5% after five years. TURP still represents the gold standard for managing benign prostatic hyperplasia with decreasing complication rates. Technological alternatives such as bipolar and laser treatments may further minimize the risks of this technically difficult procedure. Show more

To present a summary of the 2013 version of the European Association of Urology guidelines on the treatment and follow-up of male lower urinary tract symptoms (LUTS). We conducted a literature search in computer databases for relevant articles published between 1966 and 31 October 2012. The Oxford classification system (2001) was used to determine the level of evidence for each article and to assign the grade of recommendation for each treatment modality. Men with mild symptoms are suitable for watchful waiting. All men with bothersome LUTS should be offered lifestyle advice prior to or concurrent with any treatment. Men with bothersome moderate-to-severe LUTS quickly benefit from α1-blockers. Men with enlarged prostates, especially those >40ml, profit from 5α-reductase inhibitors (5-ARIs) that slowly reduce LUTS and the probability of urinary retention or the need for surgery. Antimuscarinics might be considered for patients who have predominant bladder storage symptoms. The phosphodiesterase type 5 inhibitor tadalafil can quickly reduce LUTS to a similar extent as α1-blockers, and it also improves erectile dysfunction. Desmopressin can be used in men with nocturia due to nocturnal polyuria. Treatment with an α1-blocker and 5-ARI (in men with enlarged prostates) or antimuscarinics (with persistent storage symptoms) combines the positive effects of either drug class to achieve greater efficacy. Prostate surgery is indicated in men with absolute indications or drug treatment-resistant LUTS due to benign prostatic obstruction. Transurethral resection of the prostate (TURP) is the current standard operation for men with prostates 30-80ml, whereas open surgery or transurethral holmium laser enucleation is appropriate for men with prostates >80ml. Alternatives for monopolar TURP include bipolar TURP and transurethral incision of the prostate (for glands <30ml) and laser treatments. Transurethral microwave therapy and transurethral needle ablation are effective minimally invasive treatments with higher retreatment rates compared with TURP. Prostate stents are an alternative to catheterisation for men unfit for surgery. Ethanol or botulinum toxin injections into the prostate are still experimental. These symptom-oriented guidelines provide practical guidance for the management of men experiencing LUTS. The full version is available online (www.uroweb.org/gls/pdf/12_Male_LUTS.pdf).
