Bipolar enucleation of the prostate—step by step

Comparison of holmium laser enucleation with bipolar transurethral enucleation of the prostate in patients with benign prostatic hyperplasia: Results of a multicentre study

To assess the efficacy and morbidity of the holmium laser enucleation of the prostate and bipolar transurethral enucleation of the prostate in patients with benign prostatic hyperplasia. The study included 60 (55%) and 49 (45%) patients who underwent laser and bipolar enucleation of the prostate respectively. According to the perioperative data, except for length of hospital stay and enucleated prostate weight, all the remaining parameters were similar between the groups. There were significant differences between the preoperative and the postoperative third and 12th month voiding parameters in both groups. In the laser group, the maximum urine flow rate value was better than the bipolar group at the postoperative third and 12th months. However, we did not find any statistically significant difference between the groups in terms of the serum prostate-specific antigen level, International Prostate Symptom Score and postvoid residual urine volume at the postoperative third and 12th months. Our results show that both laser and bipolar techniques are effective minimally invasive surgical treatment options for men with benign prostatic hyperplasia. When compared to bipolar technique, laser technique provides shorter hospital stay, more prostatic tissue enucleation and better maximum urine flow rate values.

Complications Based on Prostate Size After Plasmakinetic Enucleation of the Prostate

BACKGROUND Lower urinary tract symptoms among adult men can significantly impact quality of life. We evaluated complications based on prostate size following plasma kinetic enucleation of the prostate. METHODS Patients were grouped into small prostate group (SPG) <75 grams, and large prostate group (LPG) >75 grams based on preoperative imaging. Patient demographics, comorbidities, preoperative international prostate symptoms score (IPSS), bother index (BI), prostate specific antigen (PSA) if indicated, post void residual volume (PVR), indwelling catheter or self-catheterization status, and any prior surgical intervention were evaluated. Postoperatively IPSS, BI, and PVR was assessed at 6 weeks, 4 months, and yearly. Post-operative urge urinary incontinence (UUI), stress urinary incontinence (SUI) and pad use was assessed. RESULTS Between September 2015 and December 2020, 296 bipolar enucleation with minimum 4 month follow-up were evaluated. All postoperative IPSS, BI, PVR and PSA timepoints were significantly decreased compared to pre-operative values (p <0.05). There was no significant difference in the complications between groups. Univariable and multivariable analysis found size <75 grams was predictive of stricture formation and bladder neck contracture. UUI was more common at 6 weeks in the SPG, and SUI was more common at 6 weeks in the LPG, but no difference was noted at the 4 month and 1 year time point. Pad use was equal between the two groups at all time points. CONCLUSIONS PKEP provides an effective treatment option for all prostate sizes, however, prostates <75 grams have a higher rate of BNC and urethral strictures compared to those >75 grams.

Holmium laser enucleation versus bipolar transurethral enucleation for treating benign prostatic hyperplasia, which one is better?

OBJECTIVE

This study aims to evaluate the overall efficacy and safety between holmium laser enucleation of the prostate (HoLEP) and bipolar transurethral enucleation of the prostate (B-TUEP) for the treatment of benign prostatic hyperplasia (BPH).

METHOD

We systematically searched electronic databases (PubMed, Scopus, Web of Science, and Cochrane Library) to identify eligible comparative studies as of July 2021. The parameters including perioperative results, complications, and functional outcomes were evaluated. RevMan version 5.4 was used for the analysis.

RESULTS

A total of 10 studies involving 1725 patients were included. HoLEP had lower operative time (p = .03), shorter catheterization time (p = .007), lower bladder irrigation time (p = .01), and higher enucleation weight (p = .01) compared with B-TUEP. However, there were no significant differences between the techniques regarding the length of stay (LOS), hemoglobin drop, transfusion rates, and complications. Furthermore, no significant differences were also observed in postoperative functional outcomes at 1, 3, 6, 12, or 24 months.

CONCLUSIONS

HoLEP has more advantages in perioperative parameters compared with B-TUEP, but no significant differences are found regarding functional outcomes and complications. Large-scale studies with long-term follow-up are required to compare the outcomes of these two techniques.

Predictors of Storage Symptom Improvement After Plasma Kinetic Enucleation of the Prostate

OBJECTIVE

To investigate which preoperative findings portend poor improvement in storage symptoms in patients undergoing plasma kinetic enucleation of prostate (PKEP).

METHODS

A single surgeon series of patients who had undergone PKEP with minimum 1 year follow up were evaluated. Patients were grouped into those with less than 33% improvement in storage symptoms (LIS) according to the international prostate symptom score (IPSS) and those with greater than 33% improvement in storage symptoms (GIS). Pre and postoperative factors were evaluated, along with IPSS, storage symptoms percentage (the total from frequency, urgency and nocturia divided by the total IPSS), bother index, and post void residual (PVR) at 6 weeks, 4 months, and yearly.

RESULTS

Two hundred sixty-eight patients had a minimum 1 year of follow up and had completed the IPSS. IPSS and bother index improved significantly from preoperatively to all time points post operatively in both groups, but the difference was greater in the GIS group. Patients in the GIS group had significantly larger prostates, more prostatic ingrowth, higher preoperative PVR, and a higher overall IPSS compared to the LIS group. Those in the LIS group had a higher incidence of prior prostate surgery, and a higher BMI. However, storage symptom percentages were equal between the GIS and LIS groups at all time points.

CONCLUSION

Greater prostatic ingrowth, larger prostate volume, higher preoperative PVR volume, and a higher overall IPSS was associated with greater improvement in storage symptoms. Prior prostate surgery and higher BMI portend less improvement in storage symptoms.

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.
