Intra-operative duplex ultrasound in renal transplantation was first described in 1998 and whilst reported in problematic cases, there are few reports of its routine use and no current published protocols. Since 2013, we have used intra-operative ultrasound in all renal transplants. The formal protocol used since August 2020 is presented as a reference document for other transplant centres. A Canon Aplio 800 ultrasound system with an i22LH8 hockey-stick transducer is used to image the renal cortex and major vessels, and an i8CX1 matrix transducer to image the graft during and after fascial closure...

OBJECTIVES: Multicystic dysplastic kidney (MCDK) is defined as the presence of multiple noncommunicating cysts of various sizes, detected sonographically, without evidence of functioning renal parenchyma on dimercaptosuccinic acid renal scan. It has an incidence of 1:4000 live births. They are more commonly diagnosed in boys, usually on the left side, but may also be bilateral. There is the presence of primitive ducts surrounded by fibromuscular connective tissue. These are because of the disturbed connection of the ureteric bud with renal blastema and abnormal division at the stage of metanephros, resulting in an abnormal metanephros differentiation...

Upper tract urothelial carcinoma (UTUC) in a duplex collecting system (DCS) is a relatively uncommon presentation with unclear management guidelines. Herein, we retrospectively reviewed all published cases of DCS with UTUC aiming to suggest personalized clinical care options for future cases. We conducted a systematic search for all cases of UTUC in DCS from published literature using the following keywords: UTUC, urothelial carcinoma (UC), collecting duct carcinoma, and DCS. The cases were summarized based on demographics, clinical presentation, predisposing risk factors, tumor location, management, and follow-up...

INTRODUCTION: Duplex renal collecting system or duplex kidney (DK) commonly is associated with uropathy, with upper pole obstruction or lower pole vesicoureteral reflux (VUR). Its management is variable, ranging from therapeutic abstention to total nephrectomy. In case of damage to a single renal pole, uretero-ureteral anastomosis (UUA) is one of the surgical techniques for preserving the pathological pole. It can be performed by laparotomy, laparoscopy, or both. The aims of this study are to report the results of UUA in pathological DK, and compare outcomes depending on the surgical approach...

INTRODUCTION: We report our initial experience with a novel ureteroplasty technique that combines the advantages of excisional tapering and folding. METHODS AND CASES: Following dissection of the megaureter, the distal ureteral end was transected at a point with an appropriate caliber to create a neo-orifice, which was left intact. Only the proximally redundant part of the ureter was excised and closed over a 10F catheter, following which the ureter was anastomosed to the bladder with an indwelling ureteral stent...

The association between a duplex renal collecting system and ectopic ureter insertion is well-established. Although congenital genitourinary abnormalities are usually detected during childhood, incidentally, or due to underlying symptoms or medical complications, a few cases might not be diagnosed/treated until adulthood. Herein, we present a case of a 43-year-old lady who came to the emergency department with acute left flank pain associated with a burning sensation during micturition for four days. Imaging showed a duplex collecting system, and findings suggestive of obstructive uropathy...

A bifid ureter is an uncommon congenital anomaly. It develops through abnormal branching of the ureteric bud in utero and represents incomplete duplication of the collecting system. However, a bifid ureter with a blind-ending branch is a rare variant. We present the case of a 26-year-old female who presented with recurrent urinary tract infections and an episode of pyelonephritis. Radiological imaging revealed a blind-ending branch of a bifid ureter with Yo-Yo reflux. This report demonstrates laparoscopic evidence of the reflux and management of this rare congenital anomaly...

OBJECTIVES: We enumerate the various laparoscopic strategies to resolve upper urinary tract (UUT) obstruction in the context of variations in anatomy and report their outcomes. PATIENTS AND METHODS: Retrospective review of primary laparoscopic UUT reconstructions performed between May 2012 and May 2021. Anomalies included: malrotated kidney (MRK), horseshoe kidney (HSK), duplex kidney (DK), pure intrarenal pelvis (IRP) and mid-ureteric stenosis (MUS). Success was defined by postoperative resolution of symptoms, improvement of anterior-posterior renal pelvic diameter (APD) on US and drainage on Mag3...

PURPOSE OF REVIEW: In this study, we describe a rare case of a male with a duplex renal collecting system with ectopic ureter insertion into the prostate who presented with sepsis and required urgent laparoscopic radical nephrectomy. This study offers urologists and emergency care practitioners a great overview of the variety of manifestations, anatomic differences, and therapeutic approaches for similar patients. RECENT FINDINGS: modified reconstructive strategy could be a method of choice when addressing particular anatomies, such as incomplete duplex kidneys with ureteropelvic junction obstruction in both upper and lower poles when the obstruction is close to the confluence of the two ureters...

Background and Objectives: Congenital ureteral stenosis is one of the leading causes of impaired urinary drainage and subsequent dilatation of the urinary collecting system, known as hydronephrosis or ureterohydronephrosis. The mechanism that leads to obstruction is not clearly known. Multiple studies in rat models have shown increased angiotensin II and TGFβ levels in obstructed ureteral tissue. The aim of the study is to investigate the expression of fibrosis-related genes in obstructive and normal ureteral tissue...

We report a case of successful endoscopic stone management in a patient with ectopic ureteric insertion. The patient had a complete duplex collecting system, with the upper moiety ureter inserting ectopically into his prostatic urethra, and an obstructing ureteric stone in the distal portion of the ectopic ureter. This made both characterisation of the patient's anatomy and initial emergency stone management challenging.The case offers several learning points for clinicians who may encounter similar situations...

INTRODUCTION: For children with duplex systems and severe hydroureteronephrosis of the upper pole, heminephrectomy is one of many suitable treatments, particularly if there is no associated lower pole reflux. Distal ureteral stump syndrome (DSS) is a very difficult complication and manifests as stump empyema, urinary tract infection and/or vulvar discharge and can occur months to years later in 10-20 percent of patients. Secondary distal ureterectomy is an extremely difficult surgery due to inflammation and adhesions...

Ureteric calculi are common urological problems. However, the management of stone disease varies considerably with patient choice and anatomy. There are few reports about ureteral calculi in patients with unilateral complete duplex kidneys managed by ureteroscopy. We hope to increase the awareness of urologists when investigating patients with similar symptoms. We present the case of a 28-year-old man with recurring left flank pain. Non-contrast computed tomography (CT) scans of the kidney showed an impacted left vesicoureteric junction stone measuring 6 mm...

A ureterocele is a congenital cystic dilatation of the intravesical ureter that may affect either a single system kidney or the upper pole of a duplex system. The position of ureteral orifice correlates with function of associated renal moiety. Ureteroceles associated with good renal function and prompt drainage or ureteroceles associated with no renal function can be managed nonoperatively. Endoscopic puncture of ureteroceles addresses most cases; iatrogenic reflux may rarely require secondary surgery. Robot-assisted laparoscopic upper pole nephroureterectomy and ureteroureterostomy procedures are rarely associated with complications...

Congenital anomalies of the kidney and urinary tract are among the most common developmental malformations. The heterogeneity of these anomalies is very high, some of them are rarely discussed in the literature. Herein, we present a case of a 5-year-old male who was found to have a combination of unilateral multicystic dysplastic kidney associated with ipsilateral ureteric bud remnant and contralateral duplex collecting system.

INTRODUCTION AND IMPORTANCE: Ectopic ureter is defined as any ureter, single or duplex, that opens in a location other than trigone of bladder. Continuous urine leakage and regular intentional voiding must point to the diagnosis of an ectopic ureter, particularly in females (Singh et al., 2022). Following successful repair of ectopic ureter, the overall long-term continence rate is satisfactory. CASE PRESENTATION: This case is reported to discuss a case of 24 yrs...

INTRODUCTION AND IMPORTANCE: Ureterocele is a congenital malformation of the ureter with dilatation in the distal part of the ureter. In most cases, this condition was present in childhood. In cases involving adults, this condition is associated with prolapse as well as the formation of stones. Prolapsed ureterocele with stone is considered to be a very rare case. We report a complex case of prolapsed ureterocele in a young female with a protruding mass in the vagina with complete pyeloureteral duplication and stone in the left ureterovesical junction...
