Bowel excretion of Technetium-99mL, L-Ethylene dicysteine masquerading as a dilated ureter in a case of pelvi-ureteric junction obstruction: Case report and review

We report a case of a 3.5-year-old girl with right-sided PUJ obstruction, wherein the tracer excretion into the cecum and ascending colon complicated the clinical picture thereby misleading the final diagnosis or treatment plan and blurring the distinction between hydronephrosis and hydroureteronephrosis. Additional investigations may be required in such cases to reach a conclusion. The authors considered reporting this case in view of the deep-rooted clinical implications toward making a correct diagnosis. Besides, the possible mechanisms to explain the presence of the tracer inside the bowel have been discussed.

We present the case of a 46-year-old man who underwent successful antegrade ureteroscopy for lithiasis in his allograft ureter. At a scheduled follow-up 15  years after transplantation, computed tomography (CT) detected a 12-mm renal stone in the renal pelvis of the transplanted kidney. During his follow-up, gross hematuria was seen; the stone moved to the ureter, causing hydronephrosis. Ultrasound and non-contrast CT revealed hydronephrosis and a 15- mm stone in the transplanted ureter. Considering the stone size, location, and the difficulty of the access to the anastomosed ureteral orifice, percutaneous ureteroscop...

While open ureteral reimplantation surgery is the gold standard for surgical correction of vesicoureteral reflux (VUR), robot-assisted laparoscopic ureteral reimplantation via an extravesical approach (RALUR-EV) has become a minimally invasive alternative. Previous studies have shown that transient hydronephrosis after open reimplantation can occur in up to 28% of patients. However, previous studies have also shown that de novo hydronephrosis after open reimplantation is not predictive of final differential renal function.

AbstractThe purpose of the study was to investigate variables that may predict ureteral stone impaction and create a new model to predict more accurately stone impaction based on preoperative NCCT findings. Data of 238 patients who underwent URS were analyzed. Stone size, stone location, Hounsfield unit (HU) value of the stone, ureteral wall thickness (UWT) and grade of hydronephrosis were recorded. HU values of the ureter which are measured proximal and distal to the stone were recorded. Subsequently, we determined the factors that could predict the stone impaction in univariate and multivariate logistic regression analys...

Rationale: Primary carcinosarcoma of the upper urinary tract is rare. Ureteral duplication is one of the most common urinary tract malformations. Additionally, the association between ureteral duplication and malignancy is unknown. To the best of our knowledge, no cases of malignant tumors diagnosed as carcinosarcoma with ureteral duplication have been reported. We herein report the case of a patient with carcinosarcoma of the ureteropelvic junction associated with incomplete ureteral duplication. Patient concerns: A 60-year-old Japanese woman presented with painless gross hematuria. She had a history of total hystere...

Conclusions: In our experience, the incidence of post-URS ureteral stricture is low. The impacted stone is the most common cause of URS complications and hence stricture formation.

Abdülkadir Kandemir, Mehmet Giray SönmezUrology Annals 2019 11(3):310-313 Ureteral catheters are frequently used in urology clinics for intrinsic or extrinsic pathologies which cause ureteral obstruction to provide urinary drainage from the kidney to the bladder. With the increase in stent use, an increase is observed in complications occurring due to ureteral stents in direct proportion with this increase, and ureteral double-J (DJ) stents forgotten in the urinary system are observed commonly in urological cases when the patients do not refer to a health institution in this condition and may cause severe proble...

Authors: Ma Z, Lu D, Zhao W, Wang H Abstract Expression levels of retinol-binding protein (RBP) and albumin (Alb) in the kidney of patients with neonatal hydronephrosis were detected to explore whether RBP and Alb can be used as diagnostic indicators for neonatal hydronephrosis. Blood and urine samples from neonates with hydronephrosis in the obstetrics and gynaecology department of Hongqi Hospital Affiliated to Mudanjiang Medical University from January 2016 to January 2018, and healthy newborns were collected. RBP and Alb levels in neonates, and the expression of IL-12 in serum of the mothers were detected by ELI...

This condition is very rare and occurs due to unrelieved obstruction of urinary flow.A 20-year-old female presented 7 days after cesarean section with tachypnea, and generalized abdominal pain. There was absent air entry over the left hemithorax. CT scan showed massive left pleural effusion and a stone obstructing renal pelvis with hydronephrosis with peri-renal collection. The pleural f...

AbstractA 58-year-old woman complaining of dyspnea and mild flank pain was admitted to our radiology department after undergoing ultrasonography in another institution. She showed hydronephrosis and left kidney swelling. We performed a contrast-enhanced computed tomography (CECT) that confirmed the hydronephrosis and revealed a widely hypoperfused left kidney, a concentric thickening of the proximal ureter, and a slight and diffuse thickening of the renal pelvic wall, with a hyperdense content in the unenhanced CT phase and poor contrast enhancement in the post-contrast phases. A proximal ipsilateral renal vein thrombosis ...
