In the following case, the ischury attracted the first and undivided attention of the patient and medical attendant: the preceding symptoms of vaginal obstruction, having escaped observation.
March 25, 1832, I was requested to visit a young lady, aged 16, who resided at a considerable distance from this town. She had been ill three days and nights, with retention of urine; and her medical attendant had been under the necessity of relieving her by the introduction of the catheter, twice daily, during that period.
