Minimally invasive management of vesicoureteric reflux (VUR) and related anomalies
Operative indications in case of vesicorenal reflux in children have become increasingly rare. The true minimally invasive spirit first necessitates an endoscopic treatment, also called the STING procedure. A ureterovesical reimplantation is required in the presence of clinical or anatomical circumstances. Dr. Paul Philippe describes the operative pneumovesicoscopy developed by CK Yeung and Jeff Valla more than 15 years ago. Despite brilliant presentations, this technique has remained very confidential, probably because of the difficulties come across by the operators when performing the procedure. It is undoubtedly a very demanding technique as far as manual expertise is concerned.
The scarcity of operative indications and the difficulties met in the realization of this surgery render the acquisition of an expertise in the field difficult. However, the technique and the tricks described by Paul Philippe are absolutely remarkable and postoperative outcomes are particularly interesting. We are truly in the context which was initially described 25 years ago when laparoscopic surgery barely started to develop. It is key to reproduce exactly what was previously performed in open surgery in a laparoscopic fashion (or in the present case using pneumovesicoscopy).

Transperitoneal ureteric reimplantation Lich-Gregoir technique for vesicoureteral reflux (VUR) in children
The Lich-Gregoir technique, still currently used in prominent Northern American centers in the nineties, had more or less fallen into disuse. Currently, the scarcity of operative indications for ureterovesical reimplantation, with the advent of the STING procedure, the real technical difficulties found during pneumovesicoscopy for Cohen procedure, the debates on long-term difficulties (e.g., in adult life) to undergo a ureteral endoluminal surgery after a previous Cohen procedure, all these reasons have led to vested and renewed interest in performing the Lich-Gregoir technique laparoscopically. The rigorous evaluation of potential functional vesical disorders is indispensable in case of bilateral surgery.

Laparoscopic management of a catecholamine-secreting paraganglioma in a 15-year-old boy
We report the case of the surgical removal of a paravesical paraganglioma located on the right vesicoureteric junction in a 15-year-old boy who was screened positive for SDHB gene mutation, which his father suffers from. Indeed, his dad died of a metastatic paraganglioma, notably including bone and cerebral metastases.
The patient has been complaining of major headaches for some time, which were triggered off during urination to the point that he held in urine as long as possible during daytime in order to avoid urinating, and this seemed to be immediately related to the onset of severe headaches.
The tumor location allowed to correctly understand the phenomenon intraoperatively since every bladder mobilization would induce abrupt bouts of high blood pressure.
Resting blood pressure did not evidence any particular anomaly. However, there were high fluctuations in blood pressure, notably when headaches were reported. The tumor was located exactly at the vesicoureteric junction. It necessitated the resection of the lower ureter and the placement of a vesical patch.
Complete surgical resection allowed to eliminate all symptoms. The patient’s clinical and biological work-up is strictly normal more than one year after the intervention.
The resection was performed without paying attention to the potential difficulties related to the type of reconstructive surgery which entailed. Reconstruction of the vesicoureteric junction was achieved without any major problem on a slightly reduced bladder. A minimal vesicoureteric reimplantation was performed according to the Lich-Gregoir technique, with bladder closure onto a vesical drain and a vesicoureteric double J catheter.
Immediate outcomes were uneventful and control performed more than one year postoperatively testified to the absence of tumor recurrence and to the very good functioning of the vesicoureteric junction.
