BACKGROUND Kidney stones in patients with autosomal dominant polycystic kidney disease are common, regarded as the consequence of the combination of anatomic abnormality and metabolic risk factors. However, complete staghorn calculus is rare in polycystic kidney disease and predicts a gloomy prognosis of kidney. For general population, recent data showed metabolic factors were the dominant caus...

Complete staghorn calculi are typically managed with percutaneous nephrolithotomy (PCNL). However, dilating nephrostomy and inserting a nephro access sheath can be difficult to perform without hydronephrosis. We reported the procedure of ureteroscopy-assisted retrograde nephrostomy (UARN) during PCNL. UARN is effective without dilating the renal collecting system in cases of complete staghorn c...

BACKGROUND Ureteric calculi are usually small and solitary.The term giant has been applied to ureteric calculi that aremore than five cms in length and/or 50g or more in weight. These are uncommon and may present with few or no urological symptoms and might be ignored or be missed. OBJECTIVE To present a rare case of a giant left ureteric calculus associated with an ipsilateral staghorn calcu...

We are reporting a young female who presented with a history of right flank pain and urinary tract infection off and on. On investigation, she was found to have a giant fork-shaped ureteral calculus in a bifid ureter. Since her ipsilateral renal unit was nonfunctioning, nephroureterectomy was performed. Such a case of giant staghorn ureteral calculus in a bifid ureter has never been reported in...

BACKGROUND Staghorn calculi are well-established risk factors for recurrent urinary tract infections (UTIs) and subsequent renal deterioration. Less commonly, long-term urothelial irritation from a calculus may also pose a risk of malignant transformation. CASE PRESENTATION A 77-year-old male with multiple medical comorbidities presented with a chronic right renal pelvic staghorn calculus and...
