Analysis of Postoperative Urinary Incontinence and Influencing Factors of Transurethral Holmium Laser Enucleation of the Prostate

INTRODUCTION

Aims of the study were to investigate the related factors of urinary incontinence after transurethral holmium laser enucleation of the prostate (HoLEP) and to provide guidance for clinical urinary control of HoLEP.

METHODS

The clinical data of 548 patients who underwent HoLEP were retrospectively analyzed. The patients were followed up for the occurrence of urinary incontinence in the short term (2 weeks), medium term (3 months), and long term (6 months) after HoLEP.

RESULTS

Among the 548 benign prostatic hyperplasia patients, 79 cases (14.42%) had urinary incontinence at 2 weeks, 19 cases (3.47%) at 3 months, and 2 cases (0.36%) at 6 months after surgery. Logistic regression analysis showed that age, prostate volume, diabetes mellitus, operation time, prostate tissue weight, and histological prostatitis were risk factors for recent urinary incontinence (p < 0.05). Age, diabetes, and operation time were risk factors for mid-term urinary incontinence (p < 0.05). The incidence of long-term urinary incontinence was low and no risk factor analysis was performed.

CONCLUSIONS

For good urinary control after HoLEP, in addition to surgery-related factors such as surgical skills, proficiency, and precise anatomy, patients' risk factors should also be paid attention to in order to improve postoperative urinary control more effectively and reduce the incidence of urinary incontinence.

Impact of diabetes mellitus on urinary continence after holmium laser enucleation of the prostate due to lower urinary tract symptoms: a retrospective study

Introduction

Diabetes mellitus (DM) is known as a risk factor of stress urinary incontinence after Holmium laser enucleation of the prostate (HoLEP). We aimed to compare the postoperative continence status of patients with and without DM, after HoLEP surgery.

Material and methods

A total of 214 patients who underwent HoLEP between January 2017 and January 2020 were retrospectively assessed. Functional outcomes, perioperative total operation time (TOT)(min), enucleation time (ET)(min), enucleation efficiency (EE)(g/min), enucleated tissue weight (ETW)(g), morcellation efficiency (ME)(g/min), morcellation time (MT)(min), continence status, intraoperative and postoperative complications according to Clavien–Dindo classification were recorded.

Results

A total of 96 patients had DM additional to benign prostate hyperplasia (BPH) (Group 1), while 118 patients had only benign prostate hyperplasia without DM (Group 2). When comparing preoperative and postoperative functional outcomes, a statistically significant improvement was observed in both groups from baseline to the 1^st and 6^th month follow-up (p ≤0.001). There were no statistically significant differences between groups in postoperative stress urinary incontinence at postoperative months 1 and 6 (1.7% vs 2.1%, p = 1 and 0.8% vs 1%, p = 1; respectively). There was no significant difference between groups in intraoperative and postoperative complications (p >0.05).

Conclusions

HoLEP is safe to perform in patients with DM at low complication and urinary incontinence rates.

State of the art on stress incontinence management after benign prostatic obstruction surgery

PURPOSE OF REVIEW

Stress urinary incontinence (SUI) is mostly seen after prostate surgery (radical prostatectomy or benign prostatic obstruction [BPO] relief). As new surgical techniques (laser, endoscopic enucleation) have been dramatically expanded in the past decade, a focus on postoperative SUI is necessary to provide the best management in this iatrogenic situation.

RECENT FINDINGS

Surgery is the main option for curative management of SUI after BPO as no oral medication is recommended. Preoperative work-up is mandatory to assess concomitant bladder dysfunction. All available surgical options (peri-urethral injections, periurethral balloons, various male slings, and artificial urinary sphincter) have been studied, but the level of evidence is very low. In this setting, SUI after BPO management is widely inspired from post-PR SUI management, mainly based on clinical experience.

SUMMARY

The available literature regarding persistent SUI after BPO relief is very scarce and further studies are warranted in this specific population.

How I Handle Retreatment of LUTS Following a Failed MIST

PURPOSE OF REVIEW

The goal of this paper is to review retreatment management after failed minimally invasive treatment (MIST) of various technologies.

RECENT FINDINGS

A failed MIST can be defined by the return, persistence, or worsening of LUTS, as documented by symptom scores. Persistence, development, or recurrence of comorbidities such as recurrent urinary tract infection (UTI), retention, stones, hematuria, and incontinence can also signal a failed MIST. The common etiology for MIST failure is the preoperative consequence of long-term bladder outlet obstruction (BOO) on the bladder function. Close monitoring of therapies with antimuscarinics or beta-agonists can be empirically utilized if post-void bladder residual (PVR) is low. If there is a high PVR, urodynamic studies and cystoscopy can be used to determine overactive bladder (OAB), BOO, or necrosis. Depending on the timing of the observed BOO/OAB, subsequent retreatments involving transurethral debridement, medical and behavioral therapies, or repeat surgical debulking can be employed.

Development and validation of a nomogram for predicting early stress urinary incontinence following endoscopic enucleation of the prostate

PURPOSE

To develop and validate a predictive nomogram for early stress urinary incontinence (SUI) after endoscopic enucleation of the prostate (EEP) in patients with benign prostatic hyperplasia (BPH).

METHODS

The records of 458 patients who underwent plasmakinetic- or diode-based EEP at our center from March 2016 to December 2019 were reviewed. Among these, 326 and 132 cases were randomly assigned to the training and validation set, respectively. A predictive nomogram was constructed based on multivariate logistic regression analysis. Receiver operating characteristic (ROC) analysis and calibration curves were employed to evaluate its performance.

RESULTS

65 years ≤ age < 70 years, 75 years ≤ age, 25 kg/m² ≤ BMI < 30 kg/m², 30 kg/m² ≤ BMI, 5 years ≤ LUTS duration, and 75 ml ≤ prostate volume were finally selected as independent predictors of early SUI into the multivariate logistics regression model. It was visualized as a concise nomogram with satisfactory discrimination and accuracy in both training and validation sets.

CONCLUSIONS

A concise nomogram was developed and validated as a useful clinical tool for predicting early SUI post-EEP.
