Percutaneous nephrolithotomy (PCNL) is a well-established treatment option for the management of kidney stones. It has evolved over time with advances in surgical technique and technology. Even for the most experienced urologists, both major and minor complications may be encountered during PCNL. Timely diagnosis and appropriate management are the keys to a favourable outcome. Here, we discuss the case of a woman aged 34 years, who underwent PCNL for a right renal staghorn stone and had an accidental puncture of the gall bladder. Post-operatively, the patient recovered well with conservative management.
