Background And Objective: Robotic approach is used widely for paediatric upper tract urinary reconstruction. This is a narrative review looking at the current status of robotic approach in lower urinary tract reconstruction. The aim of this article is to highlight the important technical aspects of commonly performed robotic lower urinary tract reconstructive surgeries and review the current literature.

Methods: : We reviewed the records of children who underwent TIPU at our institution between April 1997 and September 2007 and included only asymptomatic toilet-trained children who had an uncomplicated postoperative course and had undergone uroflometry not less than 1 year postoperatively. Unfavourable voiding parameters were either a plateau curve, a peak flow below the 5th percentile range in nomogram or a post-void residual (PVR) more than 20% of the total functional capacity of the bladder.
Article Synopsis
- The study examines the effectiveness of dye-assisted lymphatic-sparing laparoscopic varicocelectomy (LSLV) in children, highlighting its advantages over previous techniques.
- Conducted over four years, the procedure involved 25 boys with varicocele grades predominantly at 3, addressing issues like hypotrophy and pain, while successfully achieving lymphatic preservation with no complications.
- Follow-up results indicate a reduction in testicular volume differences and pain resolution, suggesting that preserving at least one lymphatic vessel during LSLV is beneficial.
Purpose: We objectively quantified the gain in urethral diameter and the effect of stenting after tubularized incised plate urethroplasty in a rabbit hypospadias model.
Materials And Methods: We created a hypospadias model in 12 New Zealand white male rabbits by excising the ventral urethra. A 3 cm tattoo line was made longitudinally in the dorsal urethral plate midline.
Purpose: Very limited literature exists on minimally invasive adrenalectomy in children. Retroperitoneoscopic adrenalectomy (RPA) has the advantage of avoiding intra-abdominal organ retraction, but concerns have been expressed regarding RPA on the right side. Herein, we describe the second reported experience with the anterior approach to RPA in children, which appears to overcome the limitations previously ascribed to right RPA.

Materials And Methods: A Chiba needle is passed percutaneously across the anterior wall of the renal pelvis after completion of the anterior pyelo-ureteric anastamotic line. A guide wire is inserted through the trocar followed by an angiocatheter over the wire.
Objectives: To review our 10-year experience with tubularized incised-plate (TIP) urethroplasty and determine the risk factors for reoperation.
Methods: The hospital records of 391 patients underwent the TIP procedure from April 1997 to September 2007 were reviewed retrospectively. Data were collected with respect to patient demographics, characteristics of the hypospadias malformation, intraoperative factors and postoperative outcome.
Purpose: We assessed whether renography should be performed routinely following pyeloplasty.
Materials And Methods: We identified the records of all patients undergoing pyeloplasty at our hospital between 1989 and 2005. Patients were eligible for the study if they had undergone preoperative ultrasound and renal scan, and postoperative ultrasound and renal scan within 3 months and 1 year postoperatively, respectively.
Background: Nonoperative treatment of blunt renal trauma in children is progressively gaining acceptance; grade 5 renal trauma is associated with a significant rate of complications.
Objective: To assess the feasibility and outcome of initial nonoperative management of grade 5 blunt renal trauma in children.
Design, Setting, And Participants: This retrospective study included 18 children (12 boys and 6 girls; mean age: 8.
Purpose: We clarified the long-term effects of extracorporeal shock wave lithotripsy on renal function and blood pressure, and its relation to body mass index and type of lithotriptor.
Materials And Methods: A total of 100 patients with a single radiopaque renal stone 2 cm or less in length were followed for 18 to 57 months (mean 43.6 +/- 13.
Objective: To evaluate the efficacy of oxidized cellulose, Surgicel(TM) (Johnson & Johnson Medical, New Brunswick, NJ, USA) for patching defects in the tunica albuginea in a rabbit model, with a future application to correct chordee.
Materials And Methods: The study comprised nine New Zealand white male rabbits; a rectangular 15 x 5-mm defect was created in the ventral tunica albuginea that was covered by Surgicel. The skin was closed with no catheters left in situ after the procedure.
Purpose: We compared the results of percutaneous nephrolithotomy and shock wave lithotripsy for the treatment of 1 to 2 cm renal stones in children.
Materials And Methods: The study included 166 children with renal stones 1 to 2 cm. A total of 75 patients (82 kidneys) were treated with percutaneous nephrolithotomy and 91 (93 kidneys) were treated with shock wave lithotripsy.
Unlabelled: We compared the role of noncontrast computerized tomography (NCCT), magnetic resonance urography (MRU), and combined abdominal radiography (KUB) and ultrasonography (US) in the diagnosis of the cause of ureteral obstruction in patients with compromised renal function.
Materials And Methods: The study included 149 patients, of whom 110 had bilateral obstruction and 39 had obstruction of a solitary kidney. Therefore, the total number of renal units was 259.
Objectives: To evaluate the role of magnetic resonance urography (MRU) and noncontrast computed tomography (NCCT) in the diagnosis of noncalcareous hydronephrosis when excretory urography (intravenous urography) is either contraindicated or inconclusive.
Methods: A total 108 consecutive patients with noncalcareous hydronephrosis were included in this study. In all patients, intravenous urography was either contraindicated or could not determine the diagnosis.
Objectives: To evaluate the role of noncontrast computed tomography (NCCT) in the determination of the cause of obstructive anuria and to compare its accuracy with that of the traditional methods of combined plain abdominal x-ray (KUB) and gray-scale abdominal ultrasonography (US).
Methods: The study included 40 consecutive patients with obstructive anuria. In addition to the routine evaluation, which included history, clinical examination, biochemical profile, KUB, and US, all patients underwent NCCT.
Objectives: To study the values of the renal resistive index (RI) before and at different points after relief of obstructive anuria and to correlate these values with the corresponding values of serum creatinine and with the recovery of renal function after release of obstruction.
Methods: A total of 32 consecutive patients with obstructive anuria were prospectively evaluated by measurement of RI before drainage and at 3 days, 1 week, 2 weeks, and 4 weeks after drainage. Serum creatinine was measured at all points of the RI examination.
