Efficacy, safety, and perioperative outcomes of holmium laser enucleation of the prostate-a comparison of patients with lower urinary tract symptoms and urinary retention.

Holmium laser enucleation of the prostate (HoLEP) is a valid treatment option to relieve bladder outlet obstruction in patients with large prostate volumes (PV). Its efficacy, tolerability, and safety are comparable to the ones of other laser treatments of the prostate and resection techniques. However, safety and efficacy of HoLEP have not been compared between patients with and without preoperative urinary retention. We included 350 patients (mean age 71.2 years) who had undergone HoLEP due to lower urinary tract symptoms (LUTS) or urinary retention caused by prostatic hyperplasia. We evaluated the differences in peri- and postoperative outcomes and complications between patients with and patients without preoperative urinary retention. The mean PV was 115 cm3. PV was > 100 cm3 in 61.9% and < 100 cm3 in 38.1% of the patients. Perioperative complications occurred in 23 patients (6.6%), 15 of which (4.3%) required operative revision. We found no significant differences in terms of complication rates between patients with PV > 100 cm3 and patients with PV < 100 cm3. Mean catheterization-duration was 3.3 days. Preoperatively, 140 patients (40%) had a suprapubic or transurethral indwelling catheter; they did not differ from patients without preoperative catheter regarding postoperative catheter removal success rate, early postoperative complications, and functional outcomes. Prostate cancer was diagnosed in 43 patients (12.3%). Median postoperative PSA-decline was 6.1 ug/l (89.8% drop). HoLEP is a safe and effective treatment for patients with LUTS or urinary retention and large PV. PV > 100 cm3 was not associated with higher complication rates or successful catheter-removal. Furthermore, functional outcomes were independent of preoperative catheterization.

Primary urethral squamous cell carcinoma: a unique manifestation of a penile tumor.

This case report describes a unique manifestation of a primary urethral squamous cell carcinoma (SCC) as the underlying pathology in an 80-year-old male patient who underwent partial penectomy due to an enlarging penile mass. Persistent pain in the right knee was discovered to be a pathologic fracture using magnetic resonance imaging. Computed tomography-guided biopsy confirmed metastatic SCC. Whole-body positron emission tomography revealed systemic dissemination to multiple sites. Orthopedic knee replacement was performed in combination with local radiotherapy. Palliative chemotherapy was rejected due to poor performance status. Primary urethral SCC is rare and an uncommon cause of advanced penile cancer. These findings could be of great interest to clinicians for two reasons. First, a tumor's appearance can be misleading. Consequently, histological work-up in accordance with clinical guidelines is necessary for accurate diagnosis. Second, a more comprehensive investigation is required when clinical symptoms persist despite the use of conventional treatment. Our case is an instance in which persistent pain masked the presence of downstream metastasis. We believe that these aforementioned points are of significant clinical importance and present a salient learning opportunity.
