Objectives To assess the safety profile of antegrade mitomycin gel instillation through a percutaneous nephrostomy tube (PCNT) for upper tract urothelial carcinoma (UTUC) with the aim of decreasing morbidity associated with therapy. Patients and Methods Patients undergoing antegrade administration of mitomycin gel via PCNT were retrospectively included for analysis from four tertiary referral centres between 2020 and 2022. The primary outcome was safety profile, as graded by Common Terminology Criteria for Adverse Events (v5.0). Post‐therapy disease burden was assessed by primary disease evaluation (PDE) via ureteroscopy. Results Thirty‐two patients received at least one dose of mitomycin gel via PCNT for UTUC, 29 of whom completed induction and underwent PDE. Thirteen patients (41%) had residual tumour present prior to induction therapy. At a median of 15.0 months following first dose of induction therapy, ureteric stenosis occurred in three patients (9%), all of whom were treated without later recurrence or chronic stenosis. Other adverse events included fatigue (27%), flank pain (19%), urinary tract infection (12%), sepsis (8%) and haematuria (8%). No patients had impaired renal function during follow‐up and there were no treatment‐related deaths. Seventeen patients (59%) had no evidence of disease at PDE and have not experienced recurrence at a median follow‐up of 13.0 months post induction. Conclusions Administration of mitomycin gel via a PCNT offers a low rate of ureteric stenosis, demonstrates a favourable safety profile, and is administered without general anaesthesia.

Purpose of review To provide an overview of how surgical benign prostatic hyperplasia (BPH) procedures are compensated in the United States and the implications of the current reimbursement system on the care of patients. Recent findings The resource-based relative value care system is Medicare's current reimbursement model. There is strong evidence that the current system does not adequately account for complex care. Consequently, for BPH surgical procedures, treatment options best suited for complex patients are not adequately reimbursed which may have implications on healthcare delivery and outcomes. Summary Inadequate reimbursement for certain BPH procedures may disincentivize the care of complex patients. Procedures such a holmium laser enucleation of the prostate are well suited for complex patients but have a steep learning curve. The incentive to learn and offer such procedures to complex patients may be unfairly influenced by reimbursement levels, which in the end penalizes patients and the treatments available to them.

Familial hypomagnesemia with hypercalciuria and nephrocalcinosis (FHHNC) is a rare tubulopathy characterized by renal loss of calcium and magnesium leading to progressive renal failure. The disorder is caused by variants to the tight junction proteins claudin-16 and -19. While rare, this disorder causes a significant burden to patients based on its clinical manifestations of various electrolyte abnormalities, nephrocalcinosis, and early progression to renal failure. In this report we describe the diagnosis of a novel variant of CLDN16 which clinically presented with severe hypomagnesemia, hypocalcemia, nephrocalcinosis, and renal failure.
