Successful management of multiple obstructing renal calculi in a 30-year-old patient with autosomal dominant polycystic kidney disease using Frequency-Doubled Double-Pulse neodymium: Yttrium - Aluminium garnet laser lithotripsy

Abstract

Autosomal dominant polycystic kidney disease (ADPKD) is the most prevalent genetic disorder that results in end-stage renal disease. Although ADPKD patients experience long disease trajectories, factors such as hypertension, proteinuria and renal calculi have been observed to lead to rapid renal function impairment in patients with ADPKD. Furthermore, due to the distorted anatomy that makes access to stone difficult, the management of nephrolithiasis in ADPKD patients is one of the several special situations in which urinary lithiasis presents management challenges. We report the case of a 30-year-old male with ADPKD and renal function impairment as a result of multiple obstructive calculi who was treated in Dialyser Medical Centre, Oshodi, Lagos, with Frequency-Doubled Double-Pulse Neodymium: Yttrium - Aluminium Garnet laser (FREDDY laser) lithotripsy, highlighting the possible advantage of FREDDY laser over other types of laser procedures given the minimal tissue-damaging potential of the laser type.
