Percutaneous unroofing of renal simple cysts: Experience from one centre.

Tehranchi A, Hamedanchi S, Badalzadeh A - Arab J Urol (2011)

Bottom Line: Simple renal cysts can be managed safely by PU, with a success rate of >90%.This technique offers several advantages over open surgery, with a shorter hospital stay, improved convalescence and reduced risk of complications.PU also avoids the multiple trocar sites, extensive dissection, and technical difficulty associated with laparoscopy.

ABSTRACT

Objective: To assess the efficacy of percutaneous unroofing (PU) for treating simple renal cysts, compared with laparoscopic decortication and open surgery.

Patients and methods: From November 2009 to October 2010, 11 patients with 12 simple cysts in renal units were managed by PU. All cysts were evaluated with ultrasonography and abdominal computed tomography. A standard transurethral resectoscope was used to resect the cyst wall, and the parenchymal portion of the cyst was subsequently cauterised. A drain was left in place for 2 days. Success was defined as a >50% reduction in cyst diameter.

Results: At the 5-month follow-up, patients were asked about their symptoms and assessed by ultrasonography. Of the 12 cyst units, eight were completely resolved, three were reduced to <50% in diameter and one was persistent, close to the original size.

Conclusion: Simple renal cysts can be managed safely by PU, with a success rate of >90%. This technique offers several advantages over open surgery, with a shorter hospital stay, improved convalescence and reduced risk of complications. PU also avoids the multiple trocar sites, extensive dissection, and technical difficulty associated with laparoscopy.

f0005: CT of a right simple renal cyst.

Mentions: All cysts were evaluated with ultrasonography (US) and abdominal CT (Fig. 1). If there was no contraindication, such as malignancy risk, abscess, pyonephrosis, peri-pelvic location and coagulopathy, the cyst wall was resected. To diagnose a benign simple cyst on US it should have a sharply defined, thin distinct smooth wall, be spherical or oval with no internal echoes, and have good transmission of sound waves, with acoustic enhancement behind the cyst (class I in the Bosniak classification) [4].
