RESUMO
OBJECTIVE: Urinothorax and urinoma are rare complications of obstructive uropathy. They might occur due to persistent high back pressure on the renal parenchyma. Urinothorax usually arises while the obstruction exists; in contrast to our case, the child presented after being operated on. He had falsely high creatinine before the operation, which was later explained by creatinine recirculation. CLINICAL PRESENTATION AND INTERVENTION: We are reporting an uncommon case of late presentation of ruptured urinoma in a 2-month-old Kuwaiti male. It led to urinothorax/uroperitoneum that caused respiratory distress and was associated with creatinine recirculation, requiring retroperitoneal perinephric catheter insertion. The child had recovered and was discharged home. CONCLUSION: A high index of suspicion is required to diagnose urinothorax, especially in patients with a history of obstructive uropathy. Aspiration of the pleural effusion will guide you to reach the diagnosis. Creatinine recirculation is rarely described in the literature. Having a patient with urinothorax/uroperitoneum should raise the suspicion of falsely elevated creatinine levels.

OBJECTIVE: Evaluation of course and outcome of pregnancies with prenatally diagnosed fetal urinoma in a single center over a 20-year period. METHODS: Retrospective study including all prenatally suspected or diagnosed fetal urinomas. Cases were analyzed by ultrasound findings during pregnancy, comparing urinomas caused by lower urinary tract obstruction (LUTO) and ureteropelvic or ureterovesical junction obstruction (UPJO/UVJO). Course of pregnancy and outcomes were compared according to the underlying etiology. RESULTS: 87 cases of fetal urinomas were identified between 2002 and 2022. The underlying etiology was LUTO in 56.3% and UPJO/UVJO in 43.7%. Complications mainly included oligo- or anhydramnios, thoracic hypoplasia as well as associated renal abnormalities. Postnatally, loss of function (LOF) in kidneys affected by urinomas was seen in 78.6% of children overall, but significantly more often in cases of UPJO/UVJO than in LUTO (86.2% vs. 70.2%, p < 0.05). CONCLUSION: Association of prenatal urinoma and postnatal LOF of the affected kidney is high, especially in cases caused by UPJO/UVJO. In survivors with urinoma caused by UPJO/UVJO, the general prognosis is excellent if the contralateral kidney was normal. In survivors with urinomas caused by LUTO, long-term prognosis depends on postnatal renal and pulmonary function.

INTRODUCTION. Chronic kidney disease is defined as the progressive, permanent and irreversible loss of renal function, one of the treatments is renal transplantation, which increases the quality of life of patients with this pathology, however, despite being one of the best therapies, it is not free of complications, especially those that occur after surgery, since they affect the proper functioning of the graft and affect its survival. OBJECTIVE. To determine the prevalence of clinical and surgical complications in immediate post-renal transplantation in order to identify the main complications that cause greater deterioration in short-term renal function. MATERIAL AND METHODS. Cross-sectional descriptive observational study, of transplanted patients under follow-up from January 2015 to December 2018 in the Renal Transplant service of the Hospital de Especialidades Carlos Andrade Marín. The sample will be the 211 cadaveric donor transplanted patients. The analyses were performed with the IBM SPSS version 25 statistical package, for which descriptive statistics were used, using tables and representing the absolute and relative values of qualitative variables, as well as measures of central tendency and variability for quantitative variables. RESULTS. We studied 193 transplanted patients of whom 49.66% had complications, of which 33. Of the clinical complications, urinary tract infection was the most prevalent with 15%, followed by acute rejection 6.7%, polyomavirus BK infections were 6.2%, acute tubular necrosis 3.16%, ending with hyperacute rejection in 1.5% and calcineurin toxicity 1.04%. Meanwhile, urological surgical complications are the most prevalent 8.8% followed by liquid collections with 6.74% and finally vascular thrombosis with 1.04%. CONCLUSIONS. The most prevalent complications are clinical vs. surgical, affecting renal function at one year with no statistically significant difference.

The kidney is the most commonly injured urinary tract organ in pediatric trauma with blunt mechanisms, causing around 80% of cases. Non-operative management (NOM) remained the first choice for minor blunt renal trauma; however, its value for major trauma is still under debate. We present three children with high-grade isolated renal trauma diagnosed using computed tomography scans and treated using NOM as the main strategy of treatment. The first patient (12-year-old) fully recovered without needing an auxiliary procedure. The second patient (6-year-old) developed urinoma and underwent percutaneous drainage of urinoma and double J stent (DJ) with an uneventful result. The third patient (14-year-old) developed urinoma and underwent percutaneous drainage and DJ stent. However, he experienced continuous hematuria that was treated via super-selective embolization. In conclusion, NOM for isolated high-grade renal trauma is feasible with good outcomes. If complications were developed during follow-up, minimally invasive procedures, such as super-selective angioembolization in continuing hemorrhage and initial drainage in urinoma, offered a comparable outcome without needing open surgery.

INTRODUCTION AND AIM: The AUA and EAU guidelines recommend re-imaging in high-grade renal trauma, regardless of the clinical findings. The aim of this study was to assess the impact of re-imaging on the overall management and outcomes in these patients. METHODS: The trauma registry of our tertiary care Level-1 trauma center was reviewed from January 2007 till October 2018. Out of 1536 patients with abdominal trauma, 174 patients with isolated renal injury were identified. Renal injuries were classified based on the AAST classification. Variables retrieved were demographics, renal injury grade, presence of urinoma, repeated imaging findings, and intervention after initial and repeated imaging. RESULTS: Low-grade injury was found in 78.7% (137/174) compared to 21.3% (37/174) with high-grade injury. The majority (n = 136) of low-grade patients were managed conservatively except one patient with Grade III injury required angioembolization after initial imaging. Of the high-grade patients, 31/37 were treated conservatively except 6/37 patients required surgical intervention after initial imaging. Following re-imaging, only one patient required surgical intervention in the form of insertion of a drainage tube for a hematoma, which was possibly infected. The existence of urinoma (5 patients) or hematoma (47 patients) was not associated with significantly higher rate of intervention (p values: 0.717 and 0.138, respectively). No significant association was noted between hematoma size and rate of intervention (p value = 0.055). CONCLUSION: Re-imaging for high-grade renal injuries could be limited to the presence of urinary extravasation in initial imaging or the presence of clinical deterioration such as pain, fever or decrease in hemoglobin level.

CASE HISTORY: Medical records were reviewed for cats that underwent surgical treatment of traumatic ureteral rupture (TUR) using urinary diversion procedures between 2012 and 2019. CLINICAL FINDINGS AND TREATMENT: Five cats had presented with injuries associated with road traffic accidents. These included three cats with abdominal hernias that required surgical management. At a median of 15 days after the accident, cats represented with lethargy, the presence of an abdominal mass or with lower urinary tract symptoms and in all cats contrast diagnostic imaging showed proximal unilateral TUR with associated para-ureteral urinoma. Four cats received subcutaneous ureteral bypass (SUB) device placement and one had ureteral anastomosis over a stent. Unilateral cyst-like retroperitoneal fluid consistent with para-ureteral urinoma was observed in all cats and a diffuse retroperitoneal haematoma was noticed in four cats. No immediate major complications occurred, and all cats had post-operative serum creatinine concentration within the reference interval. The cat that had received a ureteral stent subsequently required placement of a SUB following stent encrustation 15 months after surgery. Median follow-up time was 34 (min 28, max 58) months and renal function was normal in all cats at the last follow-up. CLINICAL RELEVANCE: Urinary diversion procedures provided long-term stable renal function following proximal TUR in these five cats. Delayed, subtle non-specific clinical signs subsequent to high-energy blunt trauma causing abdominal hernia and associated diffuse retroperitoneal haematoma, should raise suspicion of TUR. ABBREVIATIONS: AFAST: Abdominal focused assessment with sonography for trauma; SUB: Subcutaneous ureteral bypass; TUR: Traumatic ureteral rupture.

BACKGROUND: Anterior Lumbosacral Interbody Fusion (ALIF) is a type of back surgery with the advantages of direct access to the spinal interbody space and the potential lessening morbidity related to posterior approaches. PURPOSE: To describe a rare case of left ureteral lesion from ALIF surgery diagnosed 4 months after the procedure. CASE DESCRIPTION: A 37-year-old Caucasian man with a long history of painful post-traumatic spondylolisthesis and degenerative L5-S1 disc disease underwent a retroperitoneal anterior L5-S1 discectomy, insertion of an interbody tantallium cage, and placement of a pyramid titanium plate fixed with screws. Four months later, due to recurrent left lumbar pain and mild renal failure, a CT scan was performed showing left hydronephrosis with a homolateral urinoma of 17 cm in diameter. A left nephrostomy was placed and the nephrostography detected a filiform leakage at L5-S1 level in communication with the urinoma. The patient underwent laparoscopic urinoma drainage, distal left ureterectomy, and Casati-Boari flap ureterocystoneostomy with ureteral double J stent placement. The stent was held for six weeks and, 1 month later, the control ultrasound scan was negative for hydronephrosis, the creatinine level had normalized and the patient was asymptomatic. CONCLUSION: Ureteral lesion from ALIF surgery is a very rare event. Spinal surgeons should be more awareness regarding the susceptibility of ureteral injuries along with the clinical presentation, diagnostic work-up, and management options for this kind of complication.

ABSTRACT: A 53-year-old woman with cervical cancer underwent FDG PET/CT staging, which demonstrated an avid cervical mass with right parametrial involvement and presence of bilateral lymph node metastases. The right ureter was encased, resulting in obstruction and renal pelvic dilatation. Avid right renal subcapsular lesions were also noted, which were hyperintense on T2-weighted imaging compatible to encapsulated fluid collections. These lesions were diagnosed as subcapsular urinoma due to transmitted back pressure caused by obstruction of the right ureter.

BACKGROUND: Urinomas are rare and generally result from trauma to any part of the urinary collecting system. Appropriate imaging is crucial in the timely diagnosis and management of urinomas and for ruling out other etiologies such as subcapsular renal hematomas and perinephric abscesses. CASE REPORT: A 31-year-old woman with no past medical history or known trauma presented to the Emergency Department (ED) with a week of right flank pain, abdominal pain, and intermittent fevers. On point-of-care ultrasound (POCUS), she was found to have a complex right perinephric collection, later confirmed with computed tomography (CT) imaging. She was treated with intravenous (IV) antibiotics and discharged after a 3-day hospital admission with instructions to follow up with Urology. A day later, she was readmitted with worsening bilateral flank pain and persistent fevers. Image-guided percutaneous aspirations of her bilateral perinephric fluid collections revealed both urine and blood. A right ureteral stent was then placed with ultimate resolution of her symptoms. Why Should an Emergency Physician Be Aware of This? Urinomas without history of trauma are rare and should be on the differential for patients presenting with flank pain and infectious symptoms. Urinomas or other expanding perinephric fluid collections can result in superimposed infection, rupture, secondary hypertension, and renal failure. Here, we present an atypical case of atraumatic bilateral renal subcapsular urinomas with hemorrhagic components in a young and healthy woman. Our case further outlines the utility of POCUS in the ED for the timely diagnosis and management of this disease process.

Fetal urinomas are often diagnosed in prenatal ultrasonography. The etiology is usually an obstructive uropathy leading to hydronephrosis and increased intrarenal pressure putting future kidney function at risk. Rupture of pyelocaliceal system in such cases may lead to retroperitoneal urinoma or urinary ascites, sepsis, uraemia, and acute renal failure. On the other hand, this may serve as "pop-off valve" mechanism decreasing intrarenal pressure and protecting from definitive kidney function loss. We present a case of a newborn girl with a retroperitoneal urinoma, ascites, uraemia, and obstruction of a solitary right kidney, which was successfully treated minimally invasively through peritoneal and retroperitoneal drainage and intubation of the right ureter with a DJ stent shortly after birth.

Fetal urinoma is defined as an encapsulated accumulation of extravasated urine within the perirenal space or retroperitoneum. It is an uncommon finding in prenatal practice, and the vast majority of known cases are strongly associated with the existence of a urinary obstruction, such as posterior urethral valves, ureteropelvic junction obstruction, or ureterocele. We report a unique case of prenatally detected fetal bladder urinoma that occurred in the absence of an apparent obstructive uropathy, but was associated with extensive ischemic necrosis and calcifications of adjacent bladder wall, coexistent with signs of vascular supply decompensation.
