PURPOSE
Multilocular cystic nephroma is a benign entity, which requires a pathological study for a definitive
diagnosis and to discard any malignant process as a differential diagnosis. Besides being a techni-
cally difficult and demanding procedure the laparoscopic partial nephrectomy is a safe and feasible
therapeutic and diagnostic method.
MATERIAL AND METHODS
This video showed two paediatric patients with a diagnosis of simple renal cyst during a regular
study were referred for paediatric urology management. Case 1: 2 year old female with UTI and
hypertension. During a renal USG a complex renal cyst was diagnosed. Study was completed with
CT scan an MRI. Case 2: 14 year old male with abdominal pain and a simple renal cyst. During
yearly USG follow up a complex renal cyst was diagnosed. Study was completed with a CT Scan
before surgery.
RESULTS
Partial nephrectomy was carried out in both cases without incidents trans or postop. Selective
ischemia was accomplished in both cases without compromising blood flow to the entire kidney;
only one required a renal parenchymal suturing. Surgical time was 120 minutes with no bleed-
ing. Hospital in-stay was 3 days. USG controls were normal. Both cases confirmed diagnosis by
pathology.
CONCLUSIONS
Minimally invasive surgery (laparoscopic or robotic) is the best approach for partial nephrectomy
even in children. With the adequate expertise and skill is a safe and effective treatment for the
management of renal masses in paediatric patients that could be benefited by partial nephrectomy.
Nowadays this approach should be the selected technique in paediatric patients.

PURPOSE
Posterior urethral valves (PUV) are the most common cause of bladder outlet obstruction in infants.
Endoscopic management is the current standard form of treatment for PUV. The use of laser energy
is an alternative to fulgurate the obstructive tissue observed in the posterior urethral valve.
MATERIAL AND METHODS
To demonstrate in this video a fulguration of posterior urethral valve with StoneLight™ Holmium
Laser.
