title: Percutaneous nephrolithotomy in early pregnancy.
abstract: Most cases of urolithiasis in pregnancy are managed conservatively either with ureteric stents or percutaneous nephrostomy tubes, which need to be changed at regular intervals. Definitive management of the stone is usually delayed till after delivery. We describe a patient who presented with pyonephrosis in the fifth week of gestation, due to a stone obstructing the right ureteropelvic junction. This was managed by insertion of a nephrostomy tube. She declined nephrostomy tube/stent changes during the rest of her pregnancy and requested termination as an alternative. She successfully underwent percutaneous nephrolithotomy in the 14th week of pregnancy, with radiation exposure strictly localised to the kidney for 6 s. A healthy male baby was delivered at term.
