Mitrofanoff cystolitholopaxy and bladder biopsy using a mini-PCNL kit

Bladder calculi are a common complication of urinary tract augmentation with an incidence of up to 50%.1 Aside from traditional transurethral approaches, management options include lithotripsy,2 or hybrid techniques using a combination of endoscopic and laparoscopic approaches. 3 Although Mitrofanoff cystolitholopaxy has been previously described,4 we describe a further modification of the technique with concomitant bladder biopsy in a neuropathic patient using a mini-percutaneous nephrolithotomy (mini-PCNL) kit.
