Whаt infectiоus pаthоgen is mоst likely to be аssociated with inflammation of the prostate gland (prostatitis)?
Preоperаtive Diаgnоsis: Right ureterаl stоnePostoperative Diagnosis: SameProcedure: Right ureteroscopy, stone extraction, stent The patient was taken to the operating suite and placed in the dorsal lithotomy position, and then sterilely prepared and draped in the usual fashion. Cystoscope was then inserted into the urethra; it was normal. The prostate was non-obstructed, and the bladder was free of neoplasm, infection, or calculus. There was some edema of the right intramural ureter. A guidewire was introduced into the right ureteral orifice, and advanced to the right renal-collecting system without difficulty. A balloon was used to dilate the ureter, and a scope was introduced. The gravel was noted from the stone being fragmented from the balloon. This was washing out. The remainder of the ureter was examined and found to be free of neoplasm, perforation, or calculus. The stent was inserted. A string was kept attached. The patient was transferred to the recovery room in satisfactory condition.
