Abstract

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.
