He had been discharged three days earlier with a transurethral Foley catheter in the neobladder and externalized ureteral stents draining into an abdominal collection appliance.&nbsp;His postoperative course had otherwise been uncomplicated, with adequate urinary drainage before discharge.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">During the two days preceding presentation, he developed progressively worsening diffuse abdominal pain and markedly decreased urine output from both the Foley catheter and the externalized ureteral stents. The stents drained only intermittently and produced&nbsp;substantially less&nbsp;urine than previously.&nbsp;The pain was sharp, constant, and more severe on the right. He also reported chills and&nbsp;an&nbsp;inability to tolerate oral intake but denied fever.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Vital signs:\u00a0\u00a0BP 131\/81 | HR 79 | RR 14 | SpO2 97% on room air | T 36.9\u00b0C.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">On physical exam the patient appeared uncomfortable. His abdomen was diffusely tender, more prominently on the right, without\u00a0rebound\u00a0or guarding. He reported bilateral flank pain but had no costovertebral-angle tenderness.\u00a0The abdominal stent\u00a0exit\u00a0sites and surrounding skin showed no erythema, bleeding, or discharge.

The left ureteral stent was&nbsp;subsequently&nbsp;removed by interventional radiology, but the right stent could not be retrieved. Bilateral percutaneous nephrostomy tubes were therefore placed for urinary diversion.&nbsp;Urine cultures showed no growth, and antibiotics were&nbsp;discontinued. The patient\u2019s serum creatinine returned to 0.73 mg\/dL, and he was discharged on postoperative day 13 with the nephrostomy tubes in place.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Discussion:\u00a0\u00a0<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Radical cystectomy may be&nbsp;required&nbsp;for the management of bladder cancer. Orthotopic neobladder reconstruction is one urinary-diversion&nbsp;option&nbsp;and may offer continence and body-image advantages in appropriately selected patients.<sup>1&nbsp;<\/sup>However, the procedure is technically complex and is associated with both early and late complications. Early complications, occurring within the first three months postoperatively, are often related to the intestinal and urinary tract and include urine leakage, bowel obstruction, and fluid collections.<sup>2&nbsp;<\/sup>Late complications include hydronephrosis, urinary tract infection, urinary calculi, bowel obstruction, vesicoureteral reflux, and neobladder rupture.&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A bedside renal POCUS examination and&nbsp;modified&nbsp;FAST examination were performed during the&nbsp;initial&nbsp;evaluation of the patient\u2019s abdominal pain, elevated serum creatinine, and decreased urine output.&nbsp;The&nbsp;FAST&nbsp;exam is most widely used in the trauma setting to detect free abdominal fluid with a pooled sensitivity and specificity of 74% and 98%, respectively.<sup>3&nbsp;<\/sup>However,&nbsp;a recent study&nbsp;utilizing a modified&nbsp;FAST&nbsp;exam to evaluate for intra-abdominal bleeding in postoperative cesarean section patients suggests it may be useful in&nbsp;selected postoperative patients. In a cohort of 61 patients, the modified&nbsp;FAST&nbsp;exam demonstrated a sensitivity of 80% and specificity of 100% for detecting intra-abdominal fluid.<sup>4&nbsp;<\/sup>Notably, all 10 false-negative examinations corresponded to \u201cscant\u201d or \u201ctrace\u201d free fluid on formal imaging, and none of these patients required relaparotomy.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the present case, POCUS&nbsp;demonstrated&nbsp;free intraperitoneal fluid in both upper quadrants without hydronephrosis. Ultrasound cannot reliably&nbsp;determine&nbsp;the composition of intraperitoneal fluid; therefore,&nbsp;the differential diagnosis included urine, blood, simple ascites, and an infected or sterile postoperative collection. The patient\u2019s hemodynamic stability and hemoglobin concentration made major ongoing hemorrhage less likely. In the setting of recent urinary reconstruction, markedly decreased urinary drainage, and diffuse intraperitoneal free fluid, a postoperative urinary leak became a leading consideration.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Contrast-enhanced CT with delayed excretory-phase imaging confirmed urinary contrast extravasation into the peritoneal cavity. Delayed-phase CT is particularly useful for&nbsp;identifying&nbsp;urinary leakage and distinguishing urine from other postoperative fluid collections.<sup>5<\/sup>&nbsp;In this patient, the distal ends of the ureteral stents had retracted from the neobladder lumen into the peritoneal cavity. This malposition&nbsp;likely allowed&nbsp;urine to drain into the peritoneal cavity rather than into the neobladder, producing uroperitoneum, also termed urinary ascites.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The patient\u2019s serum creatinine increased from a baseline of 0.68 mg\/dL to 2.61 mg\/dL over three days. Renal POCUS&nbsp;demonstrated&nbsp;no hydronephrosis, making substantial upper urinary tract obstruction less likely. A&nbsp;component&nbsp;of true acute kidney injury remained possible given his poor oral intake and clinical evidence of volume depletion. However, in the presence of uroperitoneum, reverse peritoneal dialysis&nbsp;likely contributed&nbsp;substantially to&nbsp;the creatinine elevation. Urinary creatinine and other solutes can diffuse across the semipermeable peritoneal membrane into the systemic circulation, producing laboratory findings that mimic acute kidney injury despite&nbsp;relatively preserved&nbsp;glomerular filtration. This phenomenon is termed pseudo-azotemia or pseudo\u2013acute kidney&nbsp;injury.<sup>6&nbsp;<\/sup>Hyperkalemia, hyponatremia, and metabolic acidosis have also been described. The return of the patient\u2019s creatinine to 0.73 mg\/dL after urinary diversion supported a substantial&nbsp;component&nbsp;of pseudo-azotemia.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Empiric antibiotics were administered because of concern for a potentially infected postoperative urinary leak. However, hematuria, pyuria, and positive leukocyte esterase should be interpreted cautiously in patients with ileal neobladders because abnormal urinalysis findings are common after urinary diversion. In a study of 185 patients with orthotopic ileal neobladders who underwent urinalysis&nbsp;18 days&nbsp;after surgery, 80% had positive leukocytes, 83.8% had positive erythrocytes, and 41% had more than 20 leukocytes per high-power field.<sup>7&nbsp;<\/sup>The&nbsp;patient\u2019s urine culture ultimately showed no growth, and antibiotics were discontinued.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this patient, abdominal pain, decreased urinary output, elevated serum creatinine, and free intraperitoneal fluid on POCUS raised early concern for a postoperative urinary leak. POCUS could not&nbsp;determine&nbsp;the composition of the fluid but&nbsp;identified&nbsp;clinically significant intraperitoneal free fluid and&nbsp;facilitated&nbsp;early urologic consultation and delayed excretory-phase CT imaging. This case highlights uroperitoneum as&nbsp;an important cause&nbsp;of abdominal pain, oliguria, and&nbsp;apparent&nbsp;acute kidney injury after urinary reconstruction. The absence of hydronephrosis does not exclude&nbsp;urinary&nbsp;diversion&nbsp;failure, and an elevated serum creatinine may partly reflect reverse peritoneal dialysis rather than impaired renal filtration alone.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>References:\u00a0\u00a0<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">1.
