# Complicated Case of a Giant Bladder Stone and Forgotten Double-J (DJ) Stent in an Otherwise Healthy Elderly Patient: A Case Report

## TL;DR

An elderly man with no known health issues had a large bladder stone and a forgotten stent, leading to complex treatment and a seizure due to low sodium.

## Contribution

This case report highlights the rare and complex complications of giant bladder stones and a long-forgotten DJ stent in an elderly patient.

## Key findings

- The patient had a giant bladder stone and a forgotten DJ stent for over 20 years.
- Treatment led to hyponatremia and a seizure, requiring hospital management.
- The patient recovered and was discharged with follow-up care.

## Abstract

Giant bladder stones, defined as stones weighing over 100 g and/or measuring more than 4 cm in diameter, are relatively uncommon compared to other types of urinary tract stones. This patient, an 85-year-old male with an unknown medical history, initially presented with urinary incontinence and hematuria. Radiological findings revealed a large prostate, a forgotten left renal double-J (DJ) stent for more than 20 years with an encrusted bladder stone, and additional calculi in the lower pole of the left kidney. The patient underwent laser cystolithotripsy, but due to the complexity of the case, a second procedure was scheduled. Following the second procedure, the patient experienced a generalized tonic-clonic seizure and subsequent loss of consciousness, which was attributed to hyponatremia. The patient received appropriate management to correct hyponatremia and antiepileptic medication to control the seizure. The patient's condition eventually improved and he was discharged home with prescribed medications and follow-up appointments. This case emphasizes the potential complications of giant bladder stones and a forgotten DJ stent in an 85-year-old male patient as a rare consequence following such a rare presentation.
