A 62 year-old male with no significant medical history, presented to the emergency department with several days of vomiting. Examination showed suprapubic fullness with tenderness to palpation and a bedside ultrasound was performed:
Ultrasound revealed moderate bilateral hydronephrosis with a relatively non-distended bladder. Labs were notable for new renal failure and the patient was admitted for continued evaluation. He was ultimately diagnosed with idiopathic retroperitoneal fibrosis with bilateral distal ureteral obstruction requiring stenting.
Anatomy of Acute Urinary Retention:
Differential Diagnosis of Acute Urinary Retention:1,2,3
85yo male with a history of prostate cancer s/p radiation and androgen deprivation therapy four years ago complicated by urethral strictures requiring chronic indwelling catheter who presented to the ED yesterday with 3 days of red urine followed by no output from catheter and abdominal pain. In the ED, the patient was found to have stable hemoglobin and creatinine and was discharged with urology follow-up after symptom resolution with catheter irrigation.
Today, the patient reports no new issues, denies abdominal/flank pain, further catheter obstruction, fevers/chills. He states that his urine has been light pink in color, without clots, and significantly more clear than the prior 3 days. He has had intermittent episodes of blood in his urine in the past, but never causing obstruction. His catheter is managed at home with regular (q3wk) changes and no recent traumatic catheterizations.
He denies any new back/bone pain or unintentional weight loss.

||Well-appearing, pleasant man in no acute distress.
||+BS, soft, NT/ND, no suprapubic tenderness, no CVAT
||Foley catheter in place draining clear-pink fluid to leg bag, no clots. No evidence of trauma to urethra, no visible skin lesions. Testes descended bilaterally, no inguinal lymphadenopathy.
85M hx CaP (2009) s/p radiation and androgen deprivation therapy with urethral strictures requiring chronic indwelling catheter presenting with macroscopic hematuria. Given patient’s history, radiation cystitis is a likely cause of his symptoms. However, given the long-standing catheter, other considerations include trauma and infection. Also, recurrence or new malignancy must be considered. Will obtain UA, UCx, and schedule patient for cystoscopy with bilateral retrograde pyelogram. Also, educated patient on how to irrigate catheter if needed and provided ED precautions should obstruction persist despite irrigation attempts. Patient’s last surveillance PSA undetectable, continue routine follow-up.
Differential Diagnosis of Macroscopic Hematuria
Important Historical Elements:
- Painless: suggests malignancy
- Painful: suggests calculi/infection
- Urinalysis: presence of dysmorphic RBC’s, RBC/WBC casts, proteinuria suggest intrinsic renal disease
- Timing: early (distal urethra), throughout (upper urinary tract), terminal (bladder neck, prostatic)
