Robot-assisted boari flap calycovesicostomy for failed uretero-pelvic junction obstruction: a novel approach to a complex problem.

Uretero-pelvic junction obstruction (UPJO) is a common condition, often presenting in adulthood in developing countries. These cases can pose significant problems owing to late presentation and complications such as infection, stones, and impaired renal function. We present the case of a 28-year-old female who presented to us with recurrent symptoms and impaired drainage following a failed open pyeloplasty and robot-assisted ureterocalycostomy for right UPJO. She was managed by robot-assisted boari flap calycovesicostomy, an innovation which helped in salvaging her kidney; ensuring good drainage in the involved kidney. To our knowledge, this is the first such case in the literature in the management of complex UPJO.
