A New Technique for Simple Renal Cyst: Cystoretroperitoneal Shunt

Abstract

Purpose. To evaluate the results of patient symptoms and radiologic outcomes of cystoretroperitoneal shunt (CRS) technique in the treatment of symptomatic simple renal cysts. Patients and Methods. In a prospective study, 37 patients with a simple renal cyst were treated with ultrasound-guided percutaneous CRS-catheter. Radiological success was indicated as no recurrence of the cyst or a reduction in cyst volume by at least half. Results. CRS technique was performed successfully in 36 patients with a simple renal cyst. The mean size of all cysts decreased from 8.8 cm (range 7 to 14) to 1.7 cm (range 0 to 9; P < .001). Symptomatic success (pain relief) was achieved in 29/36 (80.5%) of patients, and radiographic success was achieved in 23/36 (63.8%) of patients, with a median follow-up of 16 months (range 6 to 24). Conclusion. Ultrasound-guided percutaneous CRS technique for simple renal cysts is fast, safe, effective, and inexpensive.

Pure Natural Orifice Translumenal Endoscopic Surgery Management of Simple Renal Cysts: 2-Year Follow-Up Results

“…13 Laparoscopy is an effective method to manage simple renal cysts, but it is technically difficult, necessitating a long learning curve for the surgeon, expensive, and needs extensive retroperitoneal dissection. 1,14,15 Ureteroscopic marsupialization was first reported in 1991 5 as a complete transurethral natural orifice translumenal endoscopic surgery (NOTES) 16 that was significantly less invasive than percutaneous nephroscopy or laparoscopy. 4,14 Unfortunately, no large case series studies have reported on the success of this technique in the management of simple renal cysts.…”
