Zinner's syndrome is a rare developmental anomaly of Wolffian duct, comprising a triad of seminal vesicle cyst, ipsilateral renal agenesis and ejaculatory duct obstruction, first described by Zinner in 1914. Several aberrations have been reported like renal dysplasia, ectopic ureteric orifice in one of the derivatives of Wolffian duct. Usually it presents in second to fourth decade of life with symptoms of urinary bladder irritation/obstruction, cyst distension, ejaculatory duct obstruction. The diagnosis is principally based on imaging studies, usually confirmed by MRI. Treatment is based upon the persistent symptoms or complications related to it. Excision of cyst is gold standard., (© 2022 The Authors.)

Percutaneous nephrolithotomy is usually considered as safe and effective in the management of renal stones in pediatric population. Urinothorax defined as presence of urine in pleural cavity is a rare complication of percutaneous nephrolithotomy. We present a rare case of slowly developing urinothorax in a 9-year-old boy following PCNL due to migration of DJ stent into the pleural cavity. The case was managed by intracostal tube drainage and repositioning of DJ stent., (© 2022 The Authors. Published by Elsevier Inc. on behalf of University of Washington.)
