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.

Background: Pleural effusion is a common pulmonary condition affecting millions of individuals worldwide. Pleural effusion of extravascular origin (PEEVO) pertains to a pleural effusion that does not originate from the pulmonary vasculature. True prevalence of PEEVO, such as urinothorax, is unclear in view of the absence of clear diagnostic criteria. However, it has been observed to follow a bimodal age distribution, with a higher frequency in the age groups of 41-50 and 61-70 years. Additionally, it was more likely to have a unilateral right-sided presentation and occupy over two-thirds of the hemithorax. Pseudo-azotemia is a condition that causes elevated blood urea nitrogen (BUN) and creatinine (Cr) levels without actual kidney dysfunction. Case Description: We report an uncommon case of right-sided urinothorax in a middle-aged female presenting with symptoms of postoperative ileus after undergoing total abdominal hysterectomy. She subsequently developed pseudo-azotemia and right-sided pleural effusion. The patient was successfully treated with thoracentesis and chest tube placement, with prompt resolution of effusion and pseudo-azotemia. Conclusions: We aim to provide insights into the underlying pathophysiology as well as diagnostic and therapeutic modalities of urinothorax. Prompt recognition and intervention can improve outcomes by decreasing respiratory complications and shorten or avoid intensive care unit stays. Physicians should consider PEEVO within their differential when intrathoracic causes of pleural effusion have been excluded and be equipped to manage it appropriately.
RESUMO
A 63-year-old female presented with a tension urinothorax after pyeloscopy, lithotripsy, and percutaneous nephrolithotomy that manifested as dyspnea and abdominal pain. CT Thorax demonstrated a large right pleural effusion with middle and lower lobe collapse with leftward shift concerning for tension hydrothorax. Analysis of the effusion after pigtail catheter demonstrated an exudative effusion with resultant resolution of the effusion after a 5-day hospital course. This case illustrates a uniquely rare complication of percutaneous urologic intervention. We highlight this case to stress the importance of considering urinothorax as a cause for dyspnea and abdominal pain after renal and ureteric interventions.
RESUMO
Urinothorax is one of the rare causes of pleural effusion of extra-vascular origin, commonly presents with a transudative pleural effusion due to obstruction, injury or trauma to the genitourinary tract. It is not a common cause which increases the likelihood of underdiagnosis or misdiagnosis. Herein, we are presenting a 65-year-old gentleman who presented with urinary symptoms found to have urinothorax secondary to urinary tract obstruction by benign prostatic hypertrophy. This case was further complicated by urinoma and pyelonephritis. We are reporting this case to highlight the importance of including this entity in the differential diagnosis in patients who have pleural effusion especially if they presented with obstructive urinary symptoms.
RESUMO
Urinothorax, defined as urine within the pleural space, is an uncommon finding in published trauma literature. To date, there are less than ten recorded cases of non-iatrogenic trauma-induced urinothorax, most resulting from blunt traumatic injuries from motor vehicle collisions. Given the rarity of the condition, the diagnosis is often missed or delayed. Once the diagnosis is suspected, the most reliable finding is a pleural fluid to serum creatinine ratio of >1. A confirmed diagnosis of urinothorax then requires drainage of pleural fluid and management of distal ureteral obstruction. Unfortunately, the added complexity of the poly-trauma patient obscures this difficult diagnosis often leading to a delay in treatment and prolonged hospital stay. No current published literature exists on penetrating trauma as a cause of urinothorax. Here, we describe a unique case of urinothorax in a 32-year-old male as a result of penetrating trauma.

Pleural effusion of extra-vascular origin has a large differential diagnosis. Ultrasonography can be utilized alongside pleural fluid analysis to determine a pleural effusion's complexity and size, thus helping aid in both diagnostic and therapeutic management. We describe the case of a 38-year-old male with a prior medical history of neurogenic bladder and nephrolithiasis with percutaneous nephrostomy tube placed one week prior to presentation. Using ultrasonography, the nephrostomy tube was determined to be positioned within the pleural cavity with a resultant hemorrhagic pleural effusion.
RESUMO
Percutaneous nephrolithotomy is usually considered as safe and effective in the management of renal stones in pediatric population. Urinothorax defined as presence of urine in pleural cavity is a rare complication of percutaneous nephrolithotomy. We present a rare case of slowly developing urinothorax in a 9-year-old boy following PCNL due to migration of DJ stent into the pleural cavity. The case was managed by intracostal tube drainage and repositioning of DJ stent.
RESUMO
Urinothorax is a rare cause of pleural effusion, which is seen in patients with obstructive uropathy, blunt trauma, or ureteric injury during abdominal surgical procedures. Clinical symptoms may include dyspnea, chest pain, cough, fever, abdominal pain, and decreased urine output. Diagnosis is made by thoracentesis, which would reveal fluid with a urine-like odor, and pleural fluid analysis, which would show if fluid is transudative in nature with a pH lower than 7.30. Pleural fluid to serum creatine ratio of more than 1 is diagnostic for this condition. In our case, the patient underwent percutaneous nephrolithotripsy with a stent placement three days before presentation to the hospital. She was diagnosed with urinothorax, which led to further investigations, and she was found to have persistent hydronephrosis. Her condition improved after her underlying hydronephrosis was addressed with stent placement. She was discharged home in stable condition.
RESUMO
Urinothorax is an unusual cause of pleural effusion. To describe a case with urinothorax secondary to urinary system trauma. 41-year-old male readmitted to our hospital 16 days after a right percutaneous nephrolithotomy with fever, shortness of breath, chest pain and multiloculated pleural effusion confirmed by CT scan, resolved with surgical treatment. Readmitted twenty-one days later with recurrent empyema and diagnosis of reno-pleural fistula, treated with new thoracotomy and double J and urinary catheter placement. The suspected diagnosis and the multidisciplinary approach allowed to solve this rare complication.

BACKGROUND: Malignant obstruction and associated hydronephrosis is a common complication of advanced cervical cancer. Percutaneous nephrostomy (PCN) followed by antegrade stenting is often required to relieve obstruction as retrograde access fails in considerable proportion of such patients. Reno-pleural fistula is a rare complication of PCN which creates a patent connection between the renal collecting system and the thoracic cavity, and urine accumulation in the pleural space can cause pleural effusion (i.e., urinothorax). Upward or downward migration is a complication of indwelling ureteric stents. Further migration with extrusion outside of the urinary tract is uncommon. Herein we present an unprecedented case in adult of ureteric stent upward migration through a reno-pleural fistula into the thoracic cavity managed by thoracoscopy. CASE PRESENTATION: A 66-year-old female was diagnosed of advanced stage cervical cancer with suspicious bladder invasion. Given her bilateral hydronephrosis with impaired renal function, she underwent bilateral PCN and subsequent antegrade ureteric stenting. However, she presented with dyspnea, right back pain, and oliguria four days after bilateral PCN catheter removal. Computed tomography reported massive right pleural effusion and an intrathoracic ureteric stent within reno-pleural fistula. Thoracoscopy with thoracostomy was performed to remove the ureteric stent and urine in right pleural space. A week later, urinothorax had resolved and right PCN was performed again. She was discharged after regaining normal renal function with right PCN and a left ureteric stent in place. CONCLUSIONS: A reno-pleural fistula can serve as a route for ureteric stent migration and that continuous drainage of urine can cause urinothorax once the stent reaches the thoracic cavity. Anytime a supracostal approach is used for PCN, even when using small caliber catheters, clinicians should pay special attention given the risk of pleural injury and subsequent complications.

The causes of kidney disease in pediatric patients are evenly divided between congenital abnormalities of the kidney and urinary tract and acquired disorders. Nearly 10% to 15% of adults in the United States have chronic kidney disease (CKD); there are no comparable data in children. Regardless of patient age, CKD is a systemic problem that affects every organ system, including the lung. We review the tests used to diagnose and evaluate kidney disease and the main clinical syndromes that are likely to be encountered to aid the pulmonology consultant who is asked to evaluate patients with kidney disease.

A 69-year-old lady with 2 renal cell carcinomas, one sited at the upper pole of her solitary right kidney, underwent percutaneous image-guided cryoablation and developed urinothorax as a complication. This was diagnosed from pleural fluid analysis and radiology imaging with computed tomography (CT). Management included image-guided chest drain and retrograde ureteric stent insertion to divert the urine from entering the pleural cavity. CT images demonstrated a fistula between the site of renal puncture and the pleural cavity, indicating that the cryoprobes traversed the diaphragm during the procedure. This case highlights urinothorax as an unusual complication of cryoablation of renal cell carcinoma. Prompt diagnosis by interventional radiologists is crucial to avert from this potentially life-threatening complication.
RESUMO
Urinothorax is a cause of pleural effusion that is often missed due to its perceived rarity. Here, we present a case of urinothorax secondary to percutaneous nephrolithotomy resulting in lung collapse and death. This case highlights urinothorax as a cause of death, its biochemical profile, and diagnostic features on autopsy. A 39-year-old female presented to the ED with low back pain and dysuria. Abdominal and pelvic CT showed a large staghorn calculus in the right kidney which was then treated with percutaneous nephrolithotomy. On post-operative day (POD) 1, the patient was febrile, had decreased breath sounds, and complained of pain with deep inspiration. Chest x-ray revealed increased right pleural fluid. On POD 3, the patient continued to have difficulty breathing and was eventually found apneic. Resuscitation was unsuccessful. Autopsy revealed a collapsed right lung associated with a 1200 mL pleural effusion, which was cloudy, yellow, and smelled like urine. The cause of death was listed as complications of percutaneous nephrolitotomy, with urinothorax and collapse of lung. While rare, urinothoraces must be considered as a cause of pleural effusion due to risk of respiratory failure and death. Diagnosis relies on pleural fluid analysis and history, especially with regard to genitourinary obstruction and surgeries.

Urinothorax (UT) is a rare and often undiagnosed condition, defined as the presence of urine in the pleural cavity due to the retroperitoneal leakage of urine (known as urinoma) into the pleural space. It is a rare cause of pleural effusion and is secondary to traumatic or obstructive reasons. UT is usually a transudate pleural effusion. Its diagnosis requires a high degree of clinical suspicion, because the respiratory symptoms tend to be absent or mild and urological signs tend to dominate. Thoracocentesis followed by measurement of creatinine in the pleural fluid is a procedure to establish the true diagnosis. The average pleural fluid-to-serum creatinine ratio is in the range of 1.09-19.8. Pleural fluid-to-serum creatinine ratio >1 is the diagnostic criterion of UT. We report a case of UT associated with trauma.
RESUMO
Se describe el caso clínico de una paciente de 51 años de edad con antecedente de neoplasia de pulmón derecho, para lo cual recibió tratamiento con quimioterapia. Aproximadamente 3 años después comenzó a presentar dolor tipo cólico en flanco y fosa lumbar izquierdos acompañado de caída del volumen urinario, por lo que fue atendida en el Hospital General Docente Dr. Juan Bruno Zayas Alfonso de Santiago de Cuba donde se le diagnosticó cáncer de cuello uterino, etapa IIIB. Se efectuó nefrostomía percutánea izquierda y el nivel del derrame pleural desapareció al transcurrir una semana. La paciente egresó con adecuada diuresis y cifras normales de creatinina; posteriormente se le indicó radioterapia contra el cáncer ginecológico.
The case report of a 51 years patient with a history of neoplasm in the right lung is described, for which she received treatment with chemotherapy. Approximately 3 years later she began to present colic type pain in left flank and lumbar cavity accompanied by fall of the urinary volume, reason why she was assisted in Dr. Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba where she was diagnosed cervical cancer, stage IIIB. Left percutaneous nephrostomy was made and the level of pleural effusion disappeared within a week. The patient was discharged with appropriate diuresis and normal figures of creatinine; later on radiotherapy was indicated against the gynecological cancer.

Urinothorax is the presence of the urine in the pleural space. 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 the renal pelvis with hydronephrosis and peri-renal collection. The pleural fluid had high fluid creatinine level suggesting urine collection. Ureteroscopy done and double J catheter inserted. The effusion became loculated, thoracotomy and pleural decortication done.
RESUMO
Urinothorax is the presence of urine in the pleural space. It can occur at any age and is more common in males. It typically results from obstructive uropathy but can also be caused by malignancy or trauma. Urinothorax is a rare cause of transudative pleural effusion and the only cause of low pH (pH <7.4) transudative effusion. We present the case of a 51-year-old female patient who had recently undergone a urological procedure and came to the emergency department reporting shortness of breath. A chest X-ray revealed a newly developed, large, right-sided pleural effusion. Thoracentesis yielded a transudative yellow fluid of normal pH with a creatinine-to-serum creatinine ratio of 1.7. A computed tomography (CT) cystogram showed extravasated contrast material within the pelvis, from which a diagnosis of urinothorax was confirmed and treated. Urinothorax is a rare diagnosis that requires a multidisciplinaryâ¯treatment approach,â¯usually including a pulmonologist and a urologist. After the genitourinary disease is treated, the urinothorax usually resolves.
RESUMO
We present here a case of severe dyspnea after a percutaneous nephrostolithotomy, which resulted from an urinothorax, an uncommon complication of posturological procedures. Chest X-ray indicated a significant left pleural effusion, and a diagnosis was confirmed by the pleural fluid analysis. Chest tube placement did not improve the patient's clinical status; retrograde pyelogram was performed, and a stent was placed in the left ureter orifice where a narrowing was discovered. Correcting the cause of the urinothorax is the key in such cases of severe pleural effusions as seen in our case.
