Physical Examination and Workup

Upon physical examination, the patient is alert and oriented, with no evidence of acute distress. He is afebrile. His heart rate is 74 beats/min, with a regular rate and rhythm, and his blood pressure is 118/75 mm Hg. His lungs are clear to auscultation bilaterally. He exhibits no costovertebral angle tenderness on examination. He is circumcised, with a patent urethral meatus.

The patient's urine is clear and straw-colored. Urinalysis reveals the following:

  • Urine pH level: 6 (normal value, < 9)

  • Specific gravity: 1.0101 (reference range, > 1 to < 1.03)

  • Glucose, ketones, and protein: negative

  • Blood: 1+ without red blood cell (RBC) casts

  • Urobilinogen level: Normal

  • Bilirubin, leukocyte esterase, and nitrites: negative

Urine microscopy demonstrates 0-2 white blood cells per high-power field (HPF), 3-10 RBCs per HPF, and rare bacteria in the urine. Tests for sexually transmitted infections are negative, and the urine culture shows no growth.

A uroflow study reveals a voiding curve with a pattern of start/stop stream and near-complete bladder emptying.
