Abstract

We present the first reported case of holmium laser enucleation of the prostate (HoLEP) in a patient with a mucosa-embedded nitinol-based "Butterfly" prostatic retractor device and a prior Excision and Primary Anastomosis urethroplasty for bulbar stricture. Using a 22Fr minimally invasive resectoscope (MiLEP), the device was fragmented with the laser and extracted in its entirety. Prostatic enucleation and morcellation were successfully and safely completed. Morcellation is feasible but requires caution due to device interference. This study demonstrates the feasibility of small-caliber MiLEP in patients with complex anatomy and implanted prostatic devices, expanding minimally invasive options for surgically challenging BPH cases.

How strong is the evidence?

Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
