Incontinence urinaire après énucléation endoscopique de la prostate au laser Holmium : fréquence, évolution, et facteurs prédictifs de survenue

[Urinary incontinence after endoscopic enucleation of the prostate with the Holmium laser: Evolutionary aspects and associated predictive factors]

OBJECTIVE

To study the evolutionary aspects of stress urinary incontinence and urinary incontinence by urgency after HoLEP through a series of 200 consecutive cases of the same surgeon then to seek secondarily the predictive factors of occurrence in the service of urology of the Hospital Center of Martigues.

PATIENTS AND METHODS

This was a monocentric, retrospective, descriptive and analytical study conducted in the urology department of the Martigues Hospital. All patients who were treated with HoLEP for benign prostatic hypertrophy (BPH) between September 2017 and March 2021 were included in the study. Patients with an age greater than 75 years, obese (BMI>30) or with neurological disease were excluded from this study.

RESULTS

Between September 2017 and March 2021, 204 patients were included in our study. The average urinary incontinence rate was 21.2% 12.2% 7.4% and 2.7% at 1 month, 3 months, 6 months and 12 months respectively. The rate of stress urinary incontinence was 5.4%, 9.2%, 5.6% and 1.8% at 1 month, 3 months, 6 months and 12 months post HoLEP respectively. Urge urinary incontinence was estimated at 13.3%, 3%, 1.8% and 0.9% at M1, M3, M6 and M12 post-HoLEP respectively. Preoperative erectile dysfunction, delivered energy, enucleated prostate weight and total intraoperative time were statistically associated with the occurrence of stress urinary incontinence postoperatively. The operative time and a low operative Qmax were statistically associated with the occurrence of postoperative stress urinary incontinence.

CONCLUSION

HoLEP is at risk of postoperative urinary incontinence. Preoperative information of the patients on the risk of urinary incontinence is essential.

One-year Functional Outcomes after Holmium Laser Enucleation of the Prostate (HoLEP): Introduction of a Composite Score (Hexafecta)

OBJECTIVE

To compare the efficiency (micturition symptoms, continence, erection) and safety of Holmium Laser Enucleation of the Prostate (HoLEP) with a single composite score (the Hexafecta score) one year postprocedure.

PATIENTS AND METHODS

We conducted a single-center retrospective study including all patients who had undergone HoLEP for the treatment of benign prostate hyperplasia (BPH) between May 2013 and August 2017. Data were obtained preoperatively and at the 6- and 12-month visits. We also reported all 90-day complications. The Hexafecta score included 6 criteria: peak urine flow of at least 15ml/s, 30% reduction in International Prostate Symptoms Score (IPSS) score, quality of life via the IPSS less than 2, no incontinence (International Consultation Incontinence Questionnaire), no significant change in erectile function (International Index of Erectile Function), and no grade III or more complications according to the Clavien-Dindo classification.

RESULTS

Two hundred thirty-five patients were included, of whom 197 (83.8%) completed the 12-month visit. Complete data were available to assess the Hexafecta score for 178 of them (75.7%). Most of the missing data were for uroflowmetry and the erectile function assessment. Hundred three patients (58%) met all 6 criteria, while 45 (25%) met 5 of them. None were retreated for BPH in the follow-up period. The de novo incontinence rate was 4.1%.

CONCLUSION

The Hexafecta score is a simple, transversal method for comprehensively evaluating functional outcomes after HoLEP surgery. Such an evaluation could be used to compare other types of procedures for BPH treatment.

Initial experience with holmium laser enucleation of the prostate in a urology specialist hospital in Nigeria

Background

Holmium laser enucleation of the prostate (HoLEP) is a more recent procedure for the management of Benign Prostatic Hyperplasia compared to open prostatectomy or Transurethral Resection of the Prostate. HoLEP is not commonly done in Nigeria. The objective of the study was to determine whether our initial experience with HoLEP in Abuja, favourably compared to those of other centres across the world.

Methods

A retrospective study was done on 40 patients who had HoLEP between October 2018 and December 2019. Pre- and post-operative International Prostate Symptom Score (IPSS), prostate-specific antigen (PSA), prostate sizes, maximum flow rate (Qmax) and post-void residual urine volume (PVR) were collated. The duration of irrigation, catheterization and length of hospital stay were also recorded and analysed. Complications were documented.

Results

There were improvements in IPSS from 19.67 to 5.41, PSA from 8.07 to 2.03 ng/ml,Qmax from 11.27 to 29.67 ml/min, PVR from 88.99 to 32.8 ml, while average prostate sizes reduced from 116.54 to 30.3 g after surgery. Following HoLEP, the duration of irrigation was 18.00 h, catheterization was 26.76 h and length of hospital stay was 1.82 days. Two (5.0%) patients were recatheterized, 4 (10.0%) developed post-operative bladder neck stenosis.

Conclusions

The outcome of HoLEP in our experience compared favourably with those from other centres. With adequate training and requisite equipment in resource-poor environments, technical procedures like HoLEP can be embarked on with favourable results.

The constant search for the greater good: evolving from TURP to anatomic enucleation of the prostate is a safe bet

PURPOSE

In a troubling moment in history with an ongoing world pandemic and the impending economic crises, there is today a plethora of commercially available options for the minimally invasive treatment of BPH. New industry-driven evaluation criteria of these treatments, the logical marketing hype, a short follow-up for many of them, make challenging to interpret the role they will finally adopt in the armamentarium to treat BPH.

METHOD

The author comments on recently published literature based in own experience and insight.

RESULTS AND CONCLUSIONS

In this situation, choosing to evolve from TURP to the next step of endoscopic treatment, the size-independent anatomic endoscopic enucleation of the prostate is a safe bet. It is now exceedingly feasible when the paradigm of AEEP has changed, due to better learning opportunities and technological and surgical technique modifications that have refined this procedure significantly since its inception.

The "Omega Sign": a novel HoLEP technique that improves continence outcomes after enucleation

PURPOSE

Holmium-laser enucleation of the prostate (HoLEP) has been a promising prostate surgery since its first introduction. Although there are 10 different HoLEP techniques in the literature, stress urinary incontinence (SUI) is common, because surgery is not performed based on the topographic anatomy of the external sphincter. We have developed a new HoLEP method named as the ''Omega Sign technique", which is based on the topographic anatomy of the external sphincter and could provide better continence outcomes by decreasing SUI rates.

MATERIALS AND METHODS

The data of 400 patients who underwent HoLEP by a single surgeon between May 2016 and February 2019 were retrospectively reviewed. The patients were divided into two groups, the first underwent the Gilling's technique (Group 1) and the second the novel ''Omega Sign'' technique (Group 2). Continence status and post-micturition symptoms (PMS) were evaluated according to the standards recommended by the international continence status.

RESULTS

The data of 400 HoLEP procedures between May 2016 and February 2019 were analyzed, comparing Group 1 (n = 200) and Group 2(n = 200). SUI rate was significantly lower in Group 2 at the day of catheter removal and first month (p < 0.005). In addition, urge urinary incontinence (UUI) rate and PMS were significantly lower in Group 2.

CONCLUSIONS

We could demonstrate improved continence results, comparable functional outcomes and equally minimal complications with the standard HoLEP technique. We believe that, the novel 'Omega sign' technique decreases SUI rates and will become standardised and easy to understand, thereby bringing and creating a shorter learning curve.

Safety and efficacy of male urethral slings for management of persistent stress urinary incontinence after holmium laser enucleation of the prostate

Holmium laser enucleation of the prostate gland (HoLEP) is an alternative to the traditional transurethral resection of the prostate, especially for large-volume prostates. One complication is urinary incontinence, which is usually stress urinary incontinence (SUI). Little data exist on surgical interventions for SUI after HoLEP. This retrospective case series examined the safety and possible efficacy of a midurethral sling (MUS) following HoLEP. Between January 2016 and February 2019, 610 HoLEPs were performed at our institution. Three (0.5%) had persistent, overly bothersome symptoms of SUI. All three underwent MUS placement with a transobturator AdVance^® male sling after failed pelvic floor rehabilitation. The degree of SUI was evaluated by pad use pre-HoLEP, post-HoLEP, and post-MUS placement. Surgical times for HoLEP and MUS were evaluated. No patients were using pads for incontinence before HoLEP. The average pad use was 7 post-HoLEP and 0.3 post-MUS. The average morcellated prostate was 48 g, and surgical time was 68 min (52 for enucleation and 15 for morcellation). No complications were reported with MUS placement intraoperatively or postoperatively. MUS for persistent and bothersome SUI after HoLEP shows promise as a safe and effective surgical option.

How to optimise urinary continence in anatomical endoscopic enucleation of the prostate?

The traditional transurethral resection of the prostate (TURP) is considered as gold-standard surgical treatment to relieve symptoms resulting from bladder outlet obstruction by prostate enlargement. However, with the advances of novel laser technologies and more experienced surgeon conquering the steep learning curve, anatomical endoscopic enucleation of prostate (AEEP) has become a more popular alternative surgical technique. Although AEEP has compatible functional outcome, less blood loss, shorter catheterisation duration and hospital stay, the risk of post-operative urinary incontinence (UI) is often an issue of concern. In this review, we focus on discussion about risk factors related to increased incidence of UI, some surgical tips to avoid damaging external urinary sphincter and treatment strategies to facilitate recovery of urinary continence after surgery.

Complications of anatomical endoscopic enucleation of the prostate

Transurethral resection of the prostate (TURP) remains the 'gold standard' for surgical treatment of benign prostatic obstruction (BPO). Recently, anatomical endoscopic enucleation of the prostate (AEEP) using holmium laser, thulium laser and plasma, etc., is extensively applied in clinical practice. However, perioperative complications of AEEP are inevitable in spite of lower incidence compared with TURP. This study reviewed the literature related to the aetiology, prevention and treatment of common complications of AEEP, which would contribute to the diagnosis and treatment of BPO.

Holmium laser enucleation of the prostate for the treatment of size-independent BPH: A single-center experience of 600 cases

OBJECTIVE

Holmium laser enucleation of the prostate (HoLEP) is an endourologic minimal invasive intervention of benign prostate hyperplasia (BPH). The interest on HoLEP is increasing in the literature. The aim of the present study was to evaluate the learning curve and our preliminary results.

MATERIAL AND METHODS

A retrospective analysis on 600 patients with BPH who underwent HoLEP between July 2015 and April 2019 was performed. Perioperative measures including enucleation efficiency (EE), morcellation efficiency (ME), and percentage of resected tissue weight (PRW) were recorded. Hospitalization time (HT) and catheterization time (CT) were measured. Functional outcomes, Clavien-Dindo classification complications, and continence status were assessed at 1-, 3-, and 6-month follow-up.

RESULTS

The mean age, prostate size, and prostate-specific antigen levels of the patients were 64.54 years, 91 g, and 4.54 ng/mL, respectively. There were 38.3% of patients with ≥100 g prostate size. The measured EE, ME, and PRW were 1.12 g/min, 4 g/min, and 72%, respectively. The mean HT and CT were 24.53 h and 21.50 h, respectively. Functional outcomes showed significant improvement at 1-, 3-, and 6-month follow-up. Intraoperative and postoperative complications were comparable with the literature. The most common perioperative complication was superficial bladder mucosal injury (n=8, 1.33%). Only one patient had persistent stress urinary incontinence at 6-month follow-up.

CONCLUSION

As mentioned in the literature, HoLEP indications are independent from prostate size. Our results showed similarity with the literature on functional outcomes, complication rates, and continence status. With its superior results, our HoLEP series from Turkey supports that HoLEP will replace transurethral resection of the prostate as the known current gold standard.
