Giant hydronephrosis is the accumulation of more than 1 liter of urine in the renal collection system; it is a rare condition. The treatment of these patients should not be delayed. There are many causes of giant hydronephrosis. If the kidneys are nonfunctional and the patient is symptomatic, nephrectomy may be necessary. Nephrectomy can be performed using an open, laparoscopic, or robotic approach. A 35-year-old male patient presented with left lumbar pain and abdominal swelling. A nonfunctional giant hydronephrotic kidney passing the abdominal midline to the opposite side secondary to uretero-pelvic region stenosis (UPRS) was found. A transperitoneal laparoscopic nephrectomy was performed. The case and the treatment are discussed in the context of the literature.
