A 17-year-old orphan boy from Kolkata was given a new lease of life by a Mumbai doctor who successfully removed a large coconut-sized stone weighing 1 kg from an augmented urinary bladder.

Rajiv Redkar, a consultant paediatric surgeon at the S.L. Raheja Hospital, a Fortis associate hospital in Mahim, removed the calcium oxalate stone from the bladder of the boy and also reconstructed a urinary bladder during the complicated and rare surgery on June 30.
