Ureteric injuries during ureteroscopic removal of ureteric stones are not rare, though injury by triprong forceps has not yet been reported. The objective behind this presentation is that, the urologist must be aware of the types of problems that may arise, the way these problems can be prevented, and the type of treatment required if an injury occurs.
We report two cases of ureteric injuries caused by triprong stone removal forceps. One injury was due to spontaneous dismantling of triprong assembly while catching the stone fragment, while the second one was due to entrapment and disassembly of triprong forceps containing the stone fragment within. Both cases were managed by gentle and meticulous removal of triprong forceps’ dismantled parts endoscopically followed by prolonged Double J (DJ) stenting. Fortunately neither of them sustained any major ureteric injury except minimal mucosal abrasions. Both cases were followed up with DJ stent removal and retrograde pyelography, which showed normal ureteric caliber without any narrowing or dilatations. Patients were asymptomatic in follow-up period. Though infrequent, surgical misadventures during stone removal can occur. Careful attention to instrument selection and surgical techniques are helpful to reduce these complications.
