Open Decortication
Open Surgical Unroofing of Complex or Large Renal Cysts
What is Open Decortication?
Open Decortication for renal cysts is performed through a flank or retroperitoneal incision when laparoscopic surgery is not feasible — due to previous operations causing adhesions, very large cysts, complex anatomy, or when nephrectomy may be needed simultaneously. The cyst is exposed under direct vision and the anterior wall widely excised, allowing the cyst cavity to collapse into the retroperitoneum. This is the most direct approach with excellent visualisation. The procedure is performed under general or spinal anaesthesia with a hospital stay of 3–5 Days.
How the Procedure Works
Incision & Access
Flank incision; retroperitoneal space developed; kidney identified within Gerota's fascia.
Cyst Identification
Cyst identified and palpated; adhesions released under direct vision.
Cyst Wall Excision
Cyst wall excised widely using scissors or electrocautery.
Haemostasis
Cyst bed inspected; bleeding points diathermed; normal parenchyma preserved.
Drain & Closure
Drain placed adjacent to the cyst bed; wound closed in layers.
Outcomes
Who Needs This Treatment?
- →Direct vision and tactile feedback in complex adhesion cases.
- →Suitable when laparoscopic access is hazardous or contraindicated.
- →Allows simultaneous renal procedures if required.
- →Excellent exposure for very large cysts or posterior pole lesions.
- →Pathological cyst wall excision provides definitive histology.
- →No equipment limitations — suitable in all surgical settings.
"Open decortication remains our fallback when laparoscopy is not safe. Direct vision in complex adhesion cases provides the confidence and control that minimally invasive surgery cannot always match."
