RESUMEN
Context: Erectile dysfunction (ED) following radical prostatectomy is a concern for patients and their partners. Low-intensity extracorporeal shockwave therapy (LI-ESWT) can potentially enhance tissue repair and regeneration. The aim of the current study was to systematically review the literature to assess the role of LI-ESWT in the management of patients with postprostatectomy ED. Evidence acquisition: Two authors independently performed a systematic search of the PubMed and Web of Science databases to identify all relevant articles. Non-English reports, case reports, reviews, letters, and editorials were excluded. Risk of bias was assessed according to the GRADE guidelines. Evidence synthesis: Nine articles met the inclusion criteria and were included in the qualitative analysis. All the studies included were published between 2015 and 2022 and the majority of them compared phosphodiesterase type 5 inhibitors (PDE5Is) alone versus a combination of LI-ESWT and PDE5Is. Only three studies were randomized controlled trials (RCTs). In general, there is no standardized protocol for LI-ESWT for postprostatectomy ED. In comparisons of LI-ESWT + PDE5Is versus PDE5Is alone, some authors found a statistically significant improvement in erectile function with LI-ESWT + PDE5Is. The starting time for LI-ESWT differed among the studies, ranging from 3 d to 6 mo after surgery. The main limitations of the review are the scarcity of studies, small sample sizes, high risk of bias, and high heterogeneity among studies. Conclusions: There is currently limited evidence on the use of LI-ESWT either alone or in combination with PDE5Is in penile rehabilitation protocols after prostatectomy. However, small clinical trials with short follow-up show that LI-ESWT could potentially play a role in the management of postprostatectomy ED in the future. Further RCTs with larger sample sizes are needed. Patient summary: Despite limited reports in the literature, low-intensity shockwave therapy after removal of the prostate is a promising noninvasive treatment for dealing with erectile dysfunction after surgery.
RESUMEN
BACKGROUND: Using the Snodgraft technique in patients with urethral plate less than 8 mm to repair distal hypospadias is still debatable. Some authors assume that augmentation may be beneficial. We aimed to compare the outcomes of the Snodgrass vs Snodgraft procedure in patients with a narrow urethral plate less than 8 mm. METHODOLOGY: This prospective randomized study included 60 children who had been treated by the Snodgrass or Snodgraft procedure for repair of distal penile hypospadias with narrow urethral plate from March 2017 to September 2018. They were randomized into two subgroups. Group 1 (30 patients) underwent tubularized incised plate urethroplasty, whereas the second group (30 patients) underwent the Snodgraft procedure by using the inner prepuce. Operative details, postoperative period, and complications were reported and statistically analyzed using IBM SPSS software package version 20.0. RESULTS: The operative time was longer for patients who underwent the Snodgraft procedure: 78 (55-95) and 110 (80-140) minutes in groups 1 and 2, respectively. In group 1, there was one case of meatal stenosis which was resolved by urethral dilation using the local anesthetic cream in the outpatient clinic. In addition, there was another case of distal penile fistula. In group 2, there was a case of complete wound disruption and another of distal penile fistula. There was no significant difference in the complication rate in any group. CONCLUSION: The operative time was longer in group 2 than in group 1 but with comparable outcomes. The Snodgraft procedure is not superior to the Snodgrass operation in the narrow healthy urethral plate.
