Upper Ureteric Stricture Secondary to Celiac Plexus Block Managed by Robotic Ureterocalicostomy.

J Endourol Case Rep 2018 3;4(1):183-185. Epub 2018 Nov 3.

Department of Urology, Asian Institute of Nephrology & Urology, Hyderabad, Telangana, India.

Ureterocalicostomy is a well-established procedure of choice for recurrent pelviureteric junction (PUJ) obstruction refractory to endoscopic management, failed pyeloplasty, completely intrarenal pelvis, and iatrogenic upper ureteral stricture with significant peripelvic fibrosis. Robotic ureterocalicostomy is the procedure of choice in such scenarios where meticulous dissection and accurate anastomotic suturing is required. We report the case of an 18-year-old male, who underwent celiac plexus block for pain management of chronic calcific pancreatitis and presented with pain in the epigastric region and the right flank.

Pathologic Specimens at Time of Pyeloplasty: Frequency and Practice Patterns.

Urology 2018 Dec 5;122:158-161. Epub 2018 Sep 5.

MUSC Department of Urology, Charleston, SC.

Objective: To assess national and regional practice patterns and rates of pathologic specimen identification sent at time of pyeloplasty, as well as project associated costs, we used a national administrative database. The rate at which the excised ureteropelvic junction obstruction (UPJO) is sent for pathologic identification is variable, arguably without a clear clinical purpose.

Materials / Methods: Utilizing a national administrative database of privately insured patients, 1496 individual cases were identified using international classification of diseases (ICD) and Current Procedural Terminology (CPT) coding. Read More

The age of robotic surgery - Is laparoscopy dead?

Arab J Urol 2018 Sep 30;16(3):262-269. Epub 2018 Jul 30.

Klinikum am Steinenberg, Reutlingen, Germany.

Introduction: Robot-assisted laparoscopic surgery (RALS) has become a widely used technology in urology. Urological procedures that are now being routinely performed robotically are: radical prostatectomy (RP), radical cystectomy (RC), renal procedures - mainly partial nephrectomy (PN), and pyeloplasty, as well as ureteric re-implantation and adrenalectomy.

Methods: This non-systematic review of the literature examines the effectiveness of RALS compared with conventional laparoscopic surgery for the most relevant urological procedures. Read More

Robot-assisted boari flap calycovesicostomy for failed uretero-pelvic junction obstruction: a novel approach to a complex problem.

J Robot Surg 2018 Aug 22. Epub 2018 Aug 22.

Department of Urology, Postgraduate Institute of Medical Education and Research, Chandigarh, 160012, India.

Uretero-pelvic junction obstruction (UPJO) is a common condition, often presenting in adulthood in developing countries. These cases can pose significant problems owing to late presentation and complications such as infection, stones, and impaired renal function. We present the case of a 28-year-old female who presented to us with recurrent symptoms and impaired drainage following a failed open pyeloplasty and robot-assisted ureterocalycostomy for right UPJO.

Hydronephrosis After Pyeloplasty: "Will It Go Away?"

Urology 2018 Nov 18;121:158-163. Epub 2018 Aug 18.

Department of Urology, Division of Pediatric Urology, Le Bonheur Children's Hospital, University of Tennessee Health Science Center, Memphis, TN. Electronic address:

Objective: To identify attributes of pediatric patients with hydronephrosis due to ureteropelvic junction obstruction and of their surgical encounters which are predictive of resolution of dilatation in order to provide more effective counseling about expected outcomes. This study was inspired by the suggestion in recent literature that greater than 20% improvement in anteroposterior diameter (APD) of the renal pelvis after pyeloplasty is indicative of resolution of obstruction. The remaining dilatation, however, is often distressing to caregivers, and there are no data to guide clinicians in counseling about its likelihood to resolve. Read More

Necrotic Lesions Following Elective Urological Surgery in an Infant.

Surg J (N Y) 2018 Jul 8;4(3):e133-e135. Epub 2018 Aug 8.

Pediatric Surgery Department, Hospital Clínico Universitario Virgen de la Arrixaca, Murcia, Spain.

 An 11-month-old female infant presented on the first postoperative (PO) day following an elective pyeloplasty, a dark bluish erythema of her lumbotomy wound, plus a satellite lesion of the same characteristics. Fever and sepsis developed, and despite broad spectrum antibiotics (meropenem and vancomycin) were started, a diagnosis of necrotizing soft-tissue infection (NSTI or necrotizing fasciitis) was established. Surgical debridement of both lesions was performed on day 3 PO, and a surgical contamination (ring retractor blade) was suspected, due to the particular geography of the lesion. Read More

Pelviureteric Junction Obstruction with Crossing Lower Polar Vessel: Indicators of Preoperative Diagnosis.

J Indian Assoc Pediatr Surg 2018 Jul-Sep;23(3):123-126

Department of Pediatric Surgery, All India Institute of Medical Sciences, New Delhi, India.

Introduction: A crossing lower polar vessel (CLPV) is found in 11%-20% of children of pelviureteric junction obstruction (PUJO). Preoperative imaging (Doppler or magnetic resonance angiography (MRA)) may help but does not form a part of routine diagnostic workup. An attempt has been made here to evaluate clinical and imaging features (ultrasound and renal dynamic scan [RDS]) in children of PUJO with CLPV and define variables that could provide a diagnostic clue to its presence.
