Previously unseen 80L giant hydronephrosis

Abstract Here we describe the case of a patient who was referred to our institution with an immense abdominal volume of unknown origin. The patient was unable to stand up and therefore was bedridden. A giant hydronephrotic kidney was diagnosed and total volume of urine removed was 80L. Nephrectomy was uneventful and, despite his acquired thoracic and abdominal deformities, he was able to recover completely. This is the largest reported hydroneprosis in the literature.
