In a patient with cirrhosis and new onset renal failure with swelling by the prostatic urethra, your dad appears to be at risk for urinary retention because of how much inflammation and swelling there is by the pelvis at the neck of the urethra. A simple noninvasive bladder scan can be done at the urologist's office after he voids or is allowed to empty his bladder completely , called a "post void residual". If there is more than 300-450 cc (every doc has their own cutoff) after a reasonable attempt to empty every last drop, he is considered to have urinary retention. This can cause urine to flow backwards and cause backpressure into the kidneys, effectively causing hydronephrosis (which can be picked up on a renal ultrasound (ultrasound of kidneys), or CT scan of the abdomen. Obstructive uropathy is this condition and can be source of renal failureAlso, ascites is not uncommon in decompensated cirrhosis. Make sure your dad is on a low salt diet. Also it is important to check a Complete metabolic panel or hepatic function panel to see his albumin level. Low albumin can contribute to ascites. Your dad could be in what we call hepatorenal syndrome if his cirrhosis is not under control and can lead to renal failure and death.
Ascites 4 weeks post-op, acute renal failureUpdate: Over 5L of fluid was drained from my dads abdomen today. The fluid was high in creatinine and consistent with urine. He initially felt much better, but then started experiencing extreme pain, likely from muscle spasms due to the drastic change in his body over the course if only 2 hours. His O2 dropped to 86 due to the pain. He is now medicated for pain and sleeping on and off. We are hoping that his status will improve over the next few days. Thank you to everyone that commented.70M, 6ft even, 205 lbs, Barrett's esophagus, eczemaHistory of heavy smoking decades ago that was reduced to once or twice per day in the 1980s.

Very active lifestyle for age including managing half acre yard, frequent 15 to 20 mile bike rides when weather permits, strength training at gym multiple times per week.January 12th, dad underwent robot assisted prostate removal. Lymph nodes were clear and there was one area where cancer had spread one millimeter into outside tissues. No radiation is recommended at this time. He was disharged home with a catheter. The catheter was removed one week later, but about 18 hours after it was removed, he was having trouble urinating and developed severe pain. He went to the ER cathed again. He was determined to have continued swelling in his urethra.A few days later, a cystogram with his surgeon revealed a small tear in his bladder where his bladder and urethra meet. His surgeon said that he expects the tear to heal on its own.My dad was admitted to the ER today for increasing discomfort in his abdominal area with pain and diarrhea. When I showed up, I noticed that his abdomen was visibly distended. CT confirmed ascites. Nothing else to note other than a 2 mm calcification in a kidney and cirrhosis. He is a recovered alcoholic that hasn't touched alcohol in 37 years. Labs shows some RBCs and WBCs in his urine. Also indicated acute kidney failure. BUN 56 mg/dL, creatinine 4.54 mg/dL, eGFR-Cr 13 mL/min/1.73m2.It is a lymphatic leak? Maybe urine leak caused it? If so, what next?
