title: Percutaneous nephroscopic management of an isolated giant renal hydatid cyst guided by single-incision laparoscopy using conventional instruments: the Santosh-PGI technique.
abstract: BACKGROUND
  Isolated renal hydatid rarely presents, but when it does occur, it requires surgical treatment. We report our experience with a novel technique involving percutaneous management of a giant renal hydatid cyst with single-incision laparoscopic assistance.
  
  
  METHODS
  First we performed retrograde ureteropyelogram, which did not show any communication between the cyst and the calyceal. A Veress needle was used for pneumoperitoneum. Three conventional laparoscopic trocars used. Under laparoscopic guidance, we punctured the cyst. The scolicidal solution used was 10% povidone-iodine. The endocyst was removed under vision with grasping forceps through the nephroscope. A Portex drain was placed into the cyst cavity.
  
  
  CONCLUSIONS
  Percutaneous aspiration and instillation of scolicidal agents followed by re-aspiration have been previously reported. This is an attractive procedure because of its acceptable success rates and reduced morbidity. In our case, simple aspiration of the cyst would not have been successful because the cyst was full of daughter cysts. Also, a blind percutaneous puncture of the cyst and dilatation could have perforated the colon or the mesocolon, which is often wrapped over the surface of such giant cysts thereby making laparoscopic guidance and mobilization of the colon imperative. We devised this unique treatment method for this patient involving three conventional ports at a single umbilical site. We believe this is the first reported case of its kind in the world. Not only this technique is minimally invasive, it is also cost-effective, as only conventional laparoscopic ports and instruments are used during the procedure.
