Article Synopsis
  • - The study investigates the outcomes of holmium laser enucleation of the prostate (HoLEP) in patients with neurologic diseases (ND) versus those without, using data from over 118 ND patients.
  • - ND patients showed higher rates of preoperative complications like indwelling catheters (57% vs. 39%) and urinary tract infections (32% vs. 19%) and had worse postoperative outcomes such as higher failure rates in void trials and acute urinary retention.
  • - Despite initially increased UTI rates in ND patients, HoLEP effectively reduced these rates and catheter use over time, though ND patients still faced higher overall complication rates than non-ND patients post-surgery.

Holmium laser enucleation of the prostate (HoLEP) is routinely performed with a 24F, 26F, or a 28F scope. Proponents of the larger scopes propose that a bigger sheath size allows for superior flow and visibility leading to a more efficient operation and better hemostasis. Those utilizing the smaller scopes suggest that the smaller sheath is less traumatic, resulting in lower stricture rates and temporary incontinence.

Article Synopsis
  • Holmium laser enucleation of the prostate (HoLEP) has proven advantages for treating benign prostatic hyperplasia (BPH), but its adoption in Medicare and similar populations remains low despite advancements allowing for same-day discharge.
  • A study analyzing data from the Nationwide Ambulatory Surgery Sample (NASS) from 2016 to 2019 revealed a 20% overall drop in BPH surgeries, yet HoLEP's usage increased from 4.7% to 8.3% of total surgeries, becoming the second most common procedure.
  • The increase in HoLEP procedures was notably seen in the South and Midwest regions, highlighting a growing acceptance of this technique even as the total number of BPH surgeries

Intradetrusor onabotulinumtoxinA (OTA) injection is a well-established treatment option for refractory overactive bladder; however, its use at the time of holmium laser enucleation of the prostate (HoLEP) for men with bladder outlet obstruction (BOO) and severe storage symptoms has not been previously reported. We retrospectively identified men with BOO and severe storage symptoms who underwent treatment with 200 U of intradetrusor OTA (Botox) at the time of HoLEP. Patients were propensity score matched to a cohort of HoLEP-only patients based on age, Michigan Incontinence Symptom Index (M-ISI) score, preoperative urinary retention, urge incontinence, and prostate size.

Purpose Of Review: Caliceal diverticula are relatively uncommon within urologic practice and may be difficult to diagnose and treat. We aim to highlight contemporary studies examining surgical interventions for patients with caliceal diverticula, with a focus on percutaneous intervention, and provide updated practical recommendations for the management of these patients.

Recent Findings: Studies within the last 3 years examining surgical treatment options for caliceal diverticular calculi are limited.

Holmium laser enucleation of the prostate (HoLEP) is a size-independent surgical option for treating benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS) with excellent, durable functional outcomes. The prevalence of LUTS secondary to BPH and prostate cancer both increase with age, although the two diseases develop independently. Urologists often face a diagnostic dilemma, as men with LUTS secondary to BPH might also present with an elevated PSA and, therefore, need a diagnostic work-up to exclude prostate cancer.

Purpose: Given increasing rates of depression in adolescents, there is a clear need for innovative treatments. In this pilot randomized clinical trial, we assessed acceptability and feasibility of two group-based interventions: yoga and cognitive-behavioral therapy (CBT). The goal of this work is to prepare for a future fully powered randomized trial to test the hypothesis that yoga is not inferior to an established adolescent depression treatment, namely, group CBT.

Chronic kidney disease (CKD) has become a worldwide burden due to the high co-morbidity and mortality. Diabetic nephropathy (DN) is one of the leading causes of CKD, and pre-dialysis is one of the most critical stages before the end-stage renal disease (ESRD). Although Chinese herbal medicine (CHM) use is not uncommon, the feasibility of using CHM among pre-dialysis DN patients remains unclear.

Background: Embolization coils have routinely been used to treat intracranial aneurysms via an endovascular approach. Soft coils are typically viewed as the best design for filling and finishing the aneurysms to achieve a higher packing density and are hypothesized to exert a lower force against the aneurysm wall during deployment. We report here an in vitro pliability test method to assess clinically relevant coil softness and compare these metrics for two commercially available framing and finishing coil products.
