Laparoscopy-assisted ureterostomy— techniqueUrinary tract anomalies in children at times pose challenges in which immediate urinary diversion is required before definitive reconstruction. Open cutaneous ureterostomy technique is a well-established approach for this scenario. We describe the laparoscopy-assisted alternative.
Ureteral clipping for the treatment of a non-functioning upper kidney moiety associated with a massive ureterocele: step-by-step description of a novel techniqueThe objective of this video is to illustrate feasibility of the ureteral ligation for the treatment of massive ureteroceles associated with non-functioning upper kidney moieties in duplex kidneys.
Laparoscopic ureterocalicostomy in children: The technique and feasibilityUreterocalicostomy is a salvage technique commonly used for failed pyeloplasties; it has also been reported as a primary procedure in ureteropelvic junction obstruction (UPJO). This video describes the technique of laparoscopic ureterocalicostomy for primary UPJO in a child with a malrotated kidney and parenchymal thinning. A 13-year-old girl with symptomatic UPJO was found to have a malrotated kidney with a high posterior insertion of the ureter. A laparoscopic dependent ureterocalicostomy over a double-J stent was performed.
Laparoscopic excision of complete bladder duplication in a 1-year-old maleComplete bladder duplication is a male predominant rare congenital malformation usually diagnosed at birth. Owing to the rarity of this anomaly, only few reports have discussed the surgical approach for this condition, with the open approach for excision being the most common. We hereby present a video of a laparoscopic resection of complete bladder and urethral duplication in a 1-year-old male.
Robot-assisted laparoscopic pyeloureterostomy in infants with duplex systems and upper pole hydronephrosis: Variations in double-J ureteral stenting techniquesWe describe our experience with robot-assisted laparoscopic (RAL) pyeloureterostomy in infants with duplex systems and upper pole hydronephrosis with an emphasis on the various double J (DJ) ureteral stent placement techniques.
Laparoscopic selective clipping of upper moiety vasculature and ureter without partial nephrectomy: A novel technique for pediatric urinary incontinence due to ectopic ureter associated with poor functioning upper renal moietyThe aim of this study was to present a novel laparoscopic technique for persistent urinary incontinence in pediatrics due to ectopic ureter associated with poor functioning upper renal moiety.
Diagnostic work-up and laparoscopic correction of an ectopic ureterA duplex renal collecting system is a common congenital anomaly in children. Continuous dribbling (especially if after the toilet-training period) should raise suspicion of the presence of an ectopic ureter, which is most often associated with ureteral duplication. This video will demonstrate the complete diagnostic work-up necessary in these cases.
Robot-assisted laparoscopic ureteral reimplantation with excisional tailoring for refluxing megaureterTo demonstrate a novel technique for robot-assisted laparoscopic excisional tailoring and reimplantation of a refluxing megaureter.
Ureteropelvic junction obstruction and calyceal diverticulum in a child with Turner syndrome and horseshoe kidneyLaparoscopic dismembered pyeloplasty for ureteropelvic junction (UPJ) obstruction is considered to be a routine procedure in many pediatric surgical centers. UPJ obstruction is known to be associated with horseshoe kidney and several reports on successful laparoscopic repair in such cases exist. The case of a 9-month-old girl with Turner syndrome is reported. A horseshoe kidney with grade 4 hydronephrosis on the left side was diagnosed by ultrasound during the neonatal period. MAG3 diuretic renography and dynamic magnetic resonance imaging nephrography revealed a differential renal function of 31% and 69% on the left and right side, respectively.
Prone retroperitoneoscopic approach for heminephrectomy: Specific advantages relating to access to vascular pedicleThe lateral approach is more widely used in retroperitoneoscopic (RP) heminephroureterectomy (HNU) due to familiar orientation and ease of conversion. The prone approach however gives early and easy access to the vascular pedicle. The main reason for not adopting a prone approach more widely is the perceived difficulty in lower ureteric access. We present a series of 30 HNUs where the prone approach was utilized extremely effectively with no conversions and few complications.
