Abstract In the present study, eighty seven selected patients with different lower urological lesions were submitted for different urological procedures,41 open and 46 endoscopic, under local anesthesia in the urology department of Benha University Hospital. All patients were SUbjected to full clinical examination, laboratory investigations, radiological examination (when indicated) which included plain U.T., intravenous urography and postvoiding film; ECG (when indicated) and urethrocystoscopy (when indicated). The age of the patients ranged from 10 to 78 years with an average of 58.3 years. TWenty-four patients (27.6%) were above the age of 60 years. Those elderly patients would require special anesthetic care if they have to be operated upon under spinal or general anesthesia. The incidence of associated medical diseases which rendered the patient of a bad anesthetic risk was 10.4%. The premedication drugs used in this study were midazolam (dormicum) 1M and meperidine (pethidine) IV. These two drugs were given to all patients 20-30 minutes prior to the procedure. In endoscopic procedures lidocaine 2% Jell (xylocaine 2%) was instilled into the urethra 10- 15 minutes after premedication. In scrotal procedures, scopolamine was given 1M with the other two drugs.The anesthetic drug used was lidocaine 1% with adrenaline 1/400,000 for all procedures expect for penile procedures where adrenaline was not used. In the present study, the route of injection of local anesthetic into the prostate was the transurethral route alone. This route twas found to be satisfactory if the resected tissue was around 15 grams. If more tissue needs to be resected, further injection of local anesthetic was needed. The procedure was successfully performed in 17 out of 20 cases of TURP. In two cases the procedure was converted to general anesthe~ia because the patients became unduly irritable and apprehensive, although the two patients accepted the idea prior to the procedure.In the third case the procedure was terminated. This patients had a chest problem and developed respiratory distress from prolonged lying supine during resection. The weight of prostatic adenomatous tissues removed from 17 patients ranged from 5 to 25 grams with an average of 11.7 grams. The operative time ranged between 40 and 90 minutes including the time consumed for injection. The average time was 58.5 minutes. There was no operative mortality and no adverse reactions attributable to the local anesthesia. Only one patient developed transient rise of blood pressure above his own previous level (150/110) the blood pressure reached (220/130). This rise of blood pressure was controlled by administration of sublingual capsule of epilate and intravenous ampoule of lasix. It was suggested that the rise of blood pressure was related to stress related to the procedure itself. The subjective pain assessment in the 17 patients was, no pain in 8 patients (47.1%), mild tolerable pain in 5 patients (29.4%), severe intolerable pain in 4 patients (23.5%). The pain tolerance was improved after injection of additional dose of local anesthetic at painful sites as well as supplemental dose of midazolam. Twelve patients underwent visual internal urethrotomy under local anesthesia. The most common site of stricture was the bulbomembranous, 5 cases. The length of stricture ranged from 0.5 to 2 em. Only one patient had a recurrent stricture. out of these 12 cases the procedure was successfully performed in 8 patients. It was discontinued in two cases in whom urethrotomy resulted in false passage.In the other two cases the procedure was terminated because of bleeding at the site of injection. It was felt that further injection will make bleeding worse particularly that the guide catheter did not pass. Both cases were submitted to general anesthesia to give room for maneuverability. The subjective pain assessment in the 12 cases was, no pain in 9 cases (75%) including the two cases complicated by false passage and the two cases who were converted to general anesthesia due to bleeding at site of injection of local anesthetic. Mild tolerable pain occurred in one patient (8%) while severe pain occurred in two patients (17%). This severe pain disappeared after injection of an extra dose of local anesthetic into the stricture. Two cases ~f midline bladder neck incision and one case of bladder neck resection for bladder neck contracture were successfully performed under local anesthesia. In the three cases the procedure was painless and no complications were reported. Transurethral resection of bladder~tumors was performed successfully in 4 out of 6 cases. The other two cases were converted to spinal anesthesia prior to completion of injection. In one of these two cases the tumor was located in the lateral bladder wall, while the other was located in the anterior bladder wall with subsequent difficulty to infiltrate both tumors circumferentially and the resection was suspected tOibe painful, therefore,both were converted to spinal anesthesia from the beginning. The tumor size in the 4 successful cases ranged from 1.5 to 3.5 cm; three of these tumors were papillary with narrow pedicle; while the fourth was nodular. The resection was painless in 3 cases (75%) where the tumor was papillary with narrow pedicle, and the tumors were excised completely. In the fourth case (25%), nodular tumor,the pain was severe and developed on deep resection. This was explained by insufficient infiltration with local anesthetic. However, the pain Qisappeared after injection of an extradose of local anesthetic. Transurethral resection of chronic bilharzial bladder ulcer was perfo~ed successfully in 5 cases. The size of resected ulcer ranged from 0.5 to 1.5 em. The site of all ulcers was posterodomal, while the shape of these ulcers was stellate (3 case~) and fissure ulcer (2 cases). The first two cases in our series experienced severe pain (40%). This, was due to inexperience with the technique. These 2 patients probably were infiltrated with insufficient amount of local anesthetic solution. However, pain disappeared after injection of an extradose of local anesthetic. Twenty one cases of scrotal procedures,hydroce1ectomy (14 cases), testicular biopsy (5 cases) and epidedemectomy (2 cases), were performed under local anesthesia. The procedure was performed successfully in all patients except one in whom exploration of the distal cord structures lead to severe pain (4.8%) which did not disappear after injection of extradose of local anesthetic and the procedure was completed under general anesthesia. This was a case of congenital hydrocele where the sac had to be followed high up in the cord above the site of injection. There were no complications attributed to local anesthetic and no vasovagal episodes.Only in some patients extensive traction on the cord lead to transient abdominal discomfort which disappeared traction. after release of such Twenty cases of different penile procedures,circumcision (8 cases), frenu10p1asty (7,cases), veno1igation (2 cases), drainage of periurethral abscess (2 cases) and repair of fracture penis (one case), were performed under local anesthesia. The procedure was successful with no pain in 19 cases (95%) while in one case (5%) it was converted to general anesthesia. This was a case of fracture penis. The patient experienced no pain on performance of circumferential incision at the dorsal aspect of the penis but on completing such incision onto the ventral aspect, he felt severe pain. Injecting an extradose of local anesthetic did not relieve such pain. This may be explained by improper injection, superficial to Buck’s fascia, so, sparing the deep dorsal nerve unanesthetised, as it was our first experience with such technique. |
