A Single Injection of Platelet-Rich Plasma Injection for the Treatment of Stress Urinary Incontinence in Females: A Randomized Placebo-Controlled Trial. Urology 2024:S0090-4295(24)00499-0. [PMID: 38942391 DOI: 10.1016/j.urology.2024.06.047] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Revised: 05/22/2024] [Accepted: 06/21/2024] [Indexed: 06/30/2024]
Abstract
OBJECTIVE To determine the efficacy of a single injection of platelet-rich plasma into the anterior vaginal wall at the mid-urethra compared to placebo, as there is emerging evidence that platelet-rich plasma may help treat female stress urinary incontinence. METHODS This was a single-blind, randomized, placebo-controlled clinical trial at a single institution. Females with bothersome, demonstrable stress-predominant urinary incontinence were enrolled. Participants were randomized to either injection of 5 mL autologous platelet-rich plasma or saline at the anterior vaginal wall at the mid-urethra. The primary outcome was composite treatment success at six months, defined as a negative cough stress test and an answer of "much better" or "very much better" on the Patient's Global Impression of Improvement. RESULTS Fifty patients were enrolled in the study and randomized to the platelet-rich plasma group (n = 25) or the saline placebo group (n = 25). There was no statistically significant difference in the primary outcome between the two groups. Adverse events were minor, and the rate of adverse events was similar between both groups. CONCLUSIONS In this randomized placebo-controlled study, we were unable to demonstrate a difference in stress urinary incontinence treatment success between platelet-rich plasma and saline injections. At this time, there is insufficient evidence to offer a one-time platelet-rich plasma injection into the anterior vaginal wall for treatment of female stress urinary incontinence.

[PMID: 37133560 DOI: 10.1007/s00192-023-05558-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Accepted: 04/04/2023] [Indexed: 05/04/2023]
Abstract
INTRODUCTION Single-incision miduretral slings (SIMS) were withdrawn from the market in many countries due to lower efficacy. In some countries they are still in use, preferred primarily because it is possible to perform the procedure under local anesthesia. Based on our previous clinical experience we postulated that local anesthesia decreased primary anchor fixation in the obturator complex. The aim of the study is to assess how local infiltration anesthesia influences anchor fixation of the tape in porcine obturator complex. METHODS The experiment was designed to determine the maximum force necessary to extract an implant anchor from a porcine obturator complex. The implant was extracted at a constant speed and data sampling frequency, and the data on displacement of the testing system, achieved force and time were recorded. The implant arms were divided into groups on the right and left sides. In the first group, the anchored arms were used for two implantations - primary and secondary without infiltration anesthesia - and in the second group they were used in the same way, using infiltration anesthesia. RESULTS A total of 40 implanted anchors were tested in the experiment, totaling ten single-incision slings (each anchor was implanted twice). An average of 8.28 N (Newton) (SD 6.73, min. 2.11, max. 30.34 N) is required to remove the implant anchor from the obturator complex without infiltration by local anesthesia. An average force of 4.40 N (SD 2.99 min. 1.2, max. 9.48) is required to remove the anchor from the obturator complex after infiltration. Local anesthesia reduces anchor fixation in the obturator complex by 47%. CONCLUSIONS The local infiltrative anesthesia decreases anchor fixation in the porcine obturator complex.

Abstract
AIMS To perform a systematic review to assess and compare the efficacy and safety of all urethral bulking agents (UBAs) available for the treatment of stress urinary incontinence (SUI) in women. METHODS This systematic review was conducted in accordance with the PRISMA guideline. A systematic search was conducted using the Ovid Medline, Embase and PubMed databases. Studies were included if they involved women who underwent either Bulkamid®, Macroplastique®, Durasphere®, Coaptite®, or Urolastic® injections for the treatment of SUI. A total of 583 articles were screened with 56 articles included. A qualitative analysis was performed. RESULTS The newer synthetic UBAs are not inferior to Contigen®, with variable mean success rates of 30%-80% in the short-term. Better long-term success rates were found with Bulkamid® (42%-70%), Coaptite® (60%-75%), and Macroplastique® (21%-80%) on qualitative review. Urinary tract infection rates were similar between bulking agents (4%-10.6%) although temporary acute urinary retention was more commonly associated with Coaptite® (mean: 34.2%), and de novo urgency in Durasphere® (mean: 24.7%). Significant complications such as migration into lymph nodes was reported with Durasphere®. Erosion was reported with Macroplastique®, Coaptite®, and Urolastic®, with a rate as high as 24.6% in one study of Urolastic®. CONCLUSION Available data support the use of Bulkamid® and Macroplastique®, which has shown a short-term efficacy of 30%-90% and 40%-85% respectively, and long-term efficacy of 42%-70%, and 21%-80%, respectively. Bulkamid® appears to have a more favorable safety profile, with no cases of erosion or migration of product associated with its use. Direct comparisons of UBAs have not been performed.

Abstract
Stress urinary incontinence (SUI), the involuntary urine leakage due to failure of the urethral closure mechanism, is a global health challenge with substantial human suffering and socioeconomic costs. Approximately 167 million male and female patients are predicted to suffer from SUI in 2018, worldwide. A wide range of surgical interventions are available for the treatment of SUI. Severe cases, however, usually require the implantation of artificial urinary sphincter devices. This review comparatively presents and analyzes the working principles, as well as the challenges, associated with the current implantable SUI systems in clinical use. These include slings, urethral bulking agents, artificial urinary sphincters, and adjustable continence devices. It further reports on recent research progress and state-of-the-art in the field of SUI implants, including an original approach proposed by the authors with a pressure feedback sensory mechanism. The new emerging field of artificial muscle devices, including electroactive polymers, provides a promising innovative solution for replacing the weakened urethral sphincter in SUI patients.

Abstract
PURPOSE OF REVIEW Stress urinary incontinence, overactive bladder, interstitial cystitis/painful bladder syndrome, and underactive bladder are highly prevalent among elderly women, and have significant impact on quality of life; however, existing treatments are limited and are not always successful for all patients. Researchers are investigating a multitude of new therapies to treat these conditions. This review will summarize the recent literature on investigative therapies for these conditions. RECENT FINDINGS Multiple new treatments are being developed for lower urinary tract dysfunction. Some of these treatments, including balloon therapy and muscle-derived stem cells for stress urinary incontinence, could provide alternatives to existing therapies. Others require further research before being used in patients, such as pudendal nerve stimulation for overactive bladder and intravesical liposomes for drug delivery in interstitial cystitis/painful bladder syndrome. SUMMARY Multiple new therapies are being investigated that could provide clinicians with additional tools to treat lower urinary tract disorders in millions of elderly women.
