International St. Mary's Hospital offers advanced Pyeloplasty using modern reconstructive urological and minimally invasive surgical techniques and individualized urinary care plans. Established in 2014, the JCI accredited hospital is located in Seoul, South Korea and has 808 beds, providing comprehensive urological, pediatric urological, and renal care for local and international patients.

Pyeloplasty is a surgical procedure used to treat ureteropelvic junction (UPJ) obstruction, a narrowing or blockage where the renal pelvis connects with the ureter. The condition can interfere with the normal drainage of urine from the kidney and may lead to hydronephrosis, recurrent urinary infections, pain, or deterioration of kidney function. During pyeloplasty, the narrowed segment is removed or repaired and the healthy ends are reconnected to create a wider pathway for urine drainage.
