My husband had a klebsiella UTI. He had 2 doses of Rocephin, 2 doses of Vancomycin, a 10 day round of Amoxicillin, two 7-day rounds of Septra. Initially the Kleb was sensitive to Amoxicillin, then not on a subsequent UA C&S. A renal/bladder US showed a less than 1 cm non-obstructing stone in the R kidney. The acute S/S of burning, difficulty starting a stream and ? fully emptying have resolved. However he has residual off and on urgency, and a bit of initial tingling . What might be causing this? He did have constipation w/Decitabine chemo for leukemia and feels he might have strained his trap door for his urine (sphincter) when straining to have a BM...possible?
