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.
