Background: Children with vesicoureteral reflux (VUR), particularly high-grade VUR, are known to be at increased risk for urinary tract infection (UTI). Current guidelines highlight certain clinical factors in the management of children with VUR; however, the clinical utility of upper tract dilation in the setting of VUR remains unclear.

Objective: The purpose of this study is to evaluate risk factors for febrile UTI (fUTI) in children with primary VUR in a modern cohort with emphasis on upper tract dilation parameters, including hydronephrosis and hydroureter.

Complications due to residual ureteral stump after upper pole heminephrectomy: A case report.

Int J Surg Case Rep

December 2024

Urology Department, Cipto Mangunkusumo Hospital/Faculty of Medicine, Universitas Indonesia, Indonesia. Electronic address:

Introduction: Surgical resection by heminephrectomy is considered the preferred treatment for duplex kidneys with non-functioning moieties. Ureteral remnant may be ligated or left in situ to avoid the risk of injury to the healthy ipsilateral ureter; however, distal redundant ureter may sometimes cause long-term complications and require further reoperation. Upper pole heminephrectomy is a surgical procedure often performed to address various renal pathologies, such as duplex kidney or non-functioning upper renal moieties.

Article Synopsis
  • Whole-exome sequencing of two siblings with multicystic dysplastic kidneys led to the discovery of a rare variant in the TSHZ3 gene, which was investigated for its association with CAKUT in humans.
  • Among CAKUT patients, those with TSHZ3 variants exhibited a higher incidence of kidney-related issues and associated developmental anomalies, suggesting that TSHZ3 plays a significant role in these conditions.

Neglected double-J stent presenting as giant bladder and ureteral stone: A case report.

Radiol Case Rep

November 2024

Department of Urology, Dr. Soetomo Hospital, Faculty of Medicine, Airlangga University, Surabaya, Indonesia.

Implementing double-J (DJ) stents in urological practice helps to alleviate kidney and ureteral obstruction. The primary causes of neglecting a DJ stent typically involve inadequate counseling and poor patient compliance. Encrustations of neglected DJ stents present a significant challenge.

The patient presented with abdominal pain for the first time 10 years ago and was diagnosed with a left ureteral calculus, left hydronephrosis, and hydroureter. The patient's abdominal pain disappeared after palliative treatment, but he refused any treatment measures for his calculus and hydrops. He was readmitted due to chronic pelvic pain 8 years ago and was diagnosed with a pelvic abscess and left renal atrophy after imaging examination.

Article Synopsis
  • A 34-year-old male experienced intermittent left flank pain and unusual urine clots, leading to the discovery of a large mass in the left kidney.
  • Imaging revealed a complex cyst that was causing hydronephrosis, prompting surgical removal and definitive diagnosis as a renal hydatid cyst.
  • This case underscores the challenge in accurately diagnosing renal hydatid cysts due to their similarity to other renal conditions, emphasizing the need for awareness in medical evaluations.

Purpose: To investigate the performance of dynamic 3D diuretic renal scintigraphy using a hybrid whole body CZT SPECT/CT for the evaluation of acute ureteric obstruction in patients with urinary stone disease.

Methods: 20 patients who presented to the Emergency Department with acute renal colic due to urinary stone disease confirmed by means of CT were prospectively included. Three observers evaluated and graded hydronephrosis, hydroureter, perirenal stranding, and thickening of the renal fascia from the CT as well as the renal scintigraphy curves from the dynamic SPECT study.

BACKGROUND Non-neurogenic neurogenic bladder involves fluctuating flow rates due to involuntary muscle contractions during voiding in those with normal neurological function. The diagnostic challenge lies in distinguishing between massive urinary bladder distension and ovarian tumors. While various pathologies mimicking ovarian tumors are documented, cases of a massively distended urinary bladder, known as giant urinary bladder, posing as such are notably scarce.

The presentation and investigation of a levopositioned caudal vena cava, a rare congenital vascular abnormality seen mainly in Bernese Mountain Dogs, which resulted in ureteral compression, hydronephrosis and hydroureter. Surgical transection, transposition and anastomosis were performed to reposition the circumcaval ureter. A 19-month-old male neutered Bernese Mountain Dog was presented with a 13-month history of vague signs including intermittent abdominal pain, inappetence and diarrhoea, which were poorly responsive to medical management.

Bladder diverticula are herniations of the bladder mucosa through the muscular layer and can be congenital or acquired. Acquired bladder diverticula are almost always associated with bladder outlet obstruction. Bladder diverticula are uncommon and often asymptomatic, however, can present with non-specific lower urinary tract symptoms, haematuria, or urinary tract infection.

Introduction: Hydronephrosis grading systems risk stratify patients with potential ureteropelvic junction obstruction, but only some criteria are measured objectively. Most notably, there is no consensus definition of renal parenchymal thinning.

Objectives: The objective of this study was to assess the association between sonographic measures of renal length, renal pelvic diameter, and renal parenchymal thickness and the outcomes of a)renal hypofunction(differential renal function{DRF} <40%) and b)high-risk renal drainage(T1/2 > 40 min).

Nephropleural fistula, a rare complication of percutaneous nephrolithotomy (PCNL), occurred in a 45-year-old male with adult autosomal dominant polycystic kidney disease (ADPKD). The patient had undergone right PCNL in 2021 and 2023 and presented to the emergency department with symptoms of fever, breathlessness, and cough lasting one week. Imaging studies, including chest radiograph and contrast-enhanced computed tomography (CECT) of the abdomen and pelvis, revealed gross right pleural effusion, right perinephric abscess, multiple renal cysts, right renal calculi and right ureteric calculi causing severe right hydronephrosis and proximal hydroureter.

March 2024

Department of Acupuncture and Moxibustion, Guang'anmen Hospital, China Academy of Chinese Medical Sciences, Beijing, China.

Background: Chronic urinary retention (CUR) resulting from lower motor neuron lesions (LMNL) is a medical condition secondary to pelvic or lumbosacral tumor resection surgeries. Electroacupuncture (EA) is proved to be effective and safe in treating certain lower urinary tract disorders. However, the clinical benefit and optimal duration of EA treatment for CUR following LMNL remain unknown.

Hydronephrotic lower moiety of duplex systems: Observations using diuresis renography.

Clin Imaging

May 2024

Division of Diagnostic Imaging and Radiology, Children's National Hospital, 111 Michigan Avenue NW, Washington, D.C. 20010, United States of America.

Article Synopsis
  • This study examines hydronephrosis in the lower part of duplex kidneys, using a technique called MAG-3 diuresis renography to assess its prevalence and behavior compared to single-system kidney obstructions.* -
  • Researchers analyzed over 5000 diuresis renograms and identified 19 affected renal units in 18 patients, noting that many cases were diagnosed before birth and showed varied drainage patterns during follow-up.* -
  • The findings suggest that hydronephrosis in duplex systems is uncommon but similar in behavior to obstructions in single kidneys, highlighting the importance of diuresis renography in diagnosis and treatment.*

Introduction: Most congenital ureteral strictures occur at the ureteropelvic or ureterovesical junction in children. Mid-ureteral stricture is very rare and can cause congenital hydronephrosis. Only a few studies have reported on coexisting mid-ureteral stricture with ipsilateral atrophic kidney in young adults.
