The interesting report by Al-Hwiesh et al. (1) on the feasibility of peritoneal dialysis (PD) in patients with an indwelling permanent suprapubic catheter (PSPC) prompted us to contribute our experience of a patient with PSPC needing renal replacement therapy.A 62-year-old woman with a history of chronic kidney disease due to a mitochondrial disorder, i.e., maternally inherited diabetes and deafness (MIDD-syndrome), presented with acute on chronic kidney injury and was found to be in acute urinary retention, with a bladder volume of more than 1,000 mL. A neuropathic origin was presumed, given her underlying condition. A transurethral catheter was placed, but when a trial without catheter failed, a PSPC was inserted. No malfunction was reported in the further course, and regular changes were undertaken without complications.Over the next year, the patient's renal function declined relentlessly. When she reached end-stage kidney disease, she opted for PD. To ascertain the extraperitoneal position of the PSPC, magnetic resonance imaging (MRI) of the lower
