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.

The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...
