Patient-1, P53-mutation, had small capsular breach, negative microscopic margin; histology was

adenoma. He had subsequent recurrences with malignant histology. 

Patient-2 had capsular breach while closing endopouch. Histology was adrenocortical-adenoma,

no recurrence at 41-months.

In open group 3-patients had distant metastasis at presentation. 1-patient had lung metastasis

7 months after surgery. One patient had local recurrence with distant metastasis 9 months after

surgery.

There were no differences in capsular breach, positive microscopic margin or local recurrence in

both groups (p-value 0.423, 0.352 and 0.480 respectively). Local recurrence in both groups were

statistically significant with capsular breach or positive microscopic margin, (p-value <0.001 and

0.003 respectively). All the metastasis/recurrences were in the adrenocortical tumours and occurred

within one-year after primary resection.

CONCLUSIONS

Outcome in terms of capsular breach and local recurrence are comparable in both groups. Capsular

breach/Microscopic positive margins are associated with higher recurrence rate. Careful en-bloc

retrieval of the specimen is important to avoid local spillage and recurrences.

PURPOSE

Post laparoscopic heminephrectomy finding of a simple cyst at the operative site is common with an

incidence of 18-60%. Cyst formation can be related to the moiety involved, the technique used to

transect the renal parenchyma or indicate incomplete removal or a breach in the residual function-

ing moiety. Routine follow-up included monitoring with serial ultrasound(USS). 

We analysed the incidence and outcome of polar cysts following minimally invasive heminephrec-

tomy (HN) in duplex kidneys utilising different techniques.

MATERIAL AND METHODS

Retrospective review from August 2000 to June 2016 of HN for duplex kidneys utilising trans(LH)

or retroperitoneal(RH) approach. Parenchymal division techniques were noted. Serial USS imaging

monitored cysts at resection margins.
