Randomized Controlled Trial Comparative Study Clinical TrialTopical anesthesia with eutetic mixture of local anesthetics cream in vasectomy: 2 randomized trials.
Two paired randomized trials testing topical anesthesia with a eutetic mixture of local anesthetics (EMLA cream*) in vasectomy were performed. In 1 trial EMLA cream was applied on 1 side of the scrotum, while infiltration anesthesia into the skin and subcutaneous tissue with mepivacaine was used on the contralateral side. All but 1 of the 13 patients (p less than 0.05) preferred infiltration anesthesia because of pain as the incision reached the subcutaneous tissue. ⋯ There was significantly less pain on the sides with the anesthetic cream (p less than 0.001). Many patients would pay the price of the cream. In conclusion, EMLA cream cannot replace but it can supplement infiltration anesthesia during vasectomy.

Comparative StudyLocal anesthesia for extracorporeal shock wave lithotripsy: a study comparing eutetic mixture of local anesthetics cream and lidocaine infiltration.
A study of the anesthetic efficacy of a eutetic mixture of local anesthetics (EMLA cream) versus lidocaine infiltration in extracorporeal shock wave lithotripsy (ESWL) was done. A total of 46 patients had 30 gm. of EMLA cream applied to the skin over the kidney and 45 had subcutaneous infiltration anesthesia with 20 ml. 1% lidocaine with epinephrine. All patients received an intravenous dose of morphine just before ESWL. ⋯ Median pain score and the amount of supplementary analgesics were not significantly different between the 2 groups. There were no significant differences between the groups with regard to post-ESWL skin changes. Therefore, EMLA cream can be recommended for ESWL provided it is applied correctly.

We examined retrospectively the records of 126 patients with blunt renal trauma to determine the criteria for radiological investigations and the imaging study of choice. Of the 3,993 patients admitted to our regional trauma unit during the last 13 years 126 (3.1%) had blunt renal trauma. Mean patient age was 32 years (range 13 to 87 years) and the male-to-female ratio was 3:1. ⋯ Therefore, the majority of patients with blunt renal trauma can be treated conservatively with an excellent result. Furthermore, radiological investigations are not needed in those with microscopic hematuria and no shock. When radiological investigations are indicated a CT scan is the imaging study of choice.

Case ReportsAbdominal cerebrospinal fluid pseudocyst: occurrence after intraperitoneal urological surgery in children with ventriculoperitoneal shunts.
Increasingly, children with ventriculoperitoneal shunts are undergoing urinary tract reconstructive surgery with bowel. The peritoneal end of the ventriculoperitoneal shunt tubing usually is exposed during the procedure, making the system vulnerable to infections and malfunction. The records of 103 myelomeningocele children with ventriculoperitoneal shunts and bowel-bladder reconstructive surgical procedures (27) were reviewed for evidence of an abdominal cerebrospinal fluid pseudocyst (6). ⋯ Additional shunt surgery was required in 5 patients with conversion to ventriculoatrial shunts. We conclude that the development of an abdominal cerebrospinal fluid pseudocyst is at least in part related to the prior abdominal surgery. Thus, pediatric urological and general surgeons caring for children with ventriculoperitoneal shunts should be aware of this complication.

Case ReportsSpinal coning after lumbar puncture in prostate cancer with asymptomatic vertebral metastasis: a case report.
A 60-year-old man was admitted to our hospital for complete urinary retention. Prostate cancer was diagnosed and anti-cancer chemotherapy was administered. Regression of prostatic enlargement was appreciated and difficult urination improved. ⋯ Complete paralysis of both lower extremities occurred postoperatively. Computerized tomography and myelographic findings demonstrated complete subarachnoid block with an extramedullary spinal cord tumor. It was concluded that traction on the spinal cord producing neurological deterioration (spinal coning) occurred after removal of the cerebrospinal fluid by lumbar puncture.
