ABSTRACT
Objective To study the value of transurethral electro-resection for renal pelvic tumor.Methods Transurethral electro-resection was performed on 11 patients after resection of the kidney.A F8 catheter was inserted into the bladder via the distal end of the ureter.The mucosal tissues around the ureter were then cut,and the ureter was fixed to the catheter and removed by pulling out the catheter.Results The operation was completed in all of the cases with a mean operation time of 115 min(65 to 170 min).None of the patients developed infection or hemorrhage after the surgery.11 patients were followed up for 6 to 18 months(mean,11 months),and no one died during the period.No tumor implantation or other intra-bladder masses were found.ConclusionsTransurethral electro-resection is feasible and safe for renal pelvic tumor.
ABSTRACT
Objective To discuss the efficacy of transurethral electro-resection combined with needle electrode treatment for bladder neck contracture after treatments of benign prostatic hyperplasia(BPH).Methods A total of 45 cases of bladder neck contracture that developed after treatments of BPH were treated with transurethral electro-resection combined with needle electrode treatment in our hospital.During the operation,the raised posterior lip of the bladder neck was cut at 6 o’clock point,and then the scar tissues at 3 and 9 o’clock points were resected to expose the bladder detrusor.The scar tissues at 12 o’clock point should be removed as much as possible so that the bladder neck could be repaired easily.Afterwards,the fibrotic ring of the bladder neck was cut through at 5 and 7 o’clock points with a needle electrode,the fat tissues covering the bladder could be exposed.Results After the operation,43 of the cases restored normal urine flow.The other 2 patients could urinate despite of mild dysuria,and the symptom was then improved by oral ?1 antagonist and M agonist.Fifteen patients developed micturition frequency and urgency,and odynuria,and were cured pontaneously in two weeks.No patient showed urinary bleeding,stricture,incontinence,or recto-vesical fistula.Follow-up was available in the patients for 3 to 30 months(mean,15 months),during the period,reexaminations showed a Qmax of 15.5-24.3 ml/s(mean,19.5),and residual urine after urination of 0-35 ml(mean,20).No relapse of bladder neck contracture occurred in this series.Conclusions Transurethral electro-resection combined with needle electrode treatment is effective for patients with bladder neck contracture after treatments of BPH.The rate of relapse is low after the operation.
ABSTRACT
Objective To investigate the efficacy and safety of hysteroscopic treatment for submucous uterine myoma.Methods From January 2000 to December 2004,a total of 168 women with submucous leiomyoma of the uterus were treated by hysteroscopy in our hospital.According to the type of the myomas,electro-resection was performed in different ways.For the patients with massive hemorrhage or older than 45 years,the endometrium was resected during the operation.Results The operation was completed in all the cases within 5 to 65 minutes mean,(27.6?12.1)minutes].The mean blood loss was(40.1?10.2)ml(8-50 ml).After the surgery,2 patients developed uterine perforation,3 had hyponatremia,and 5 showed transient fever.Among the patients,160(95.2%)were satisfied with the outcomes of the surgery.Conclusions Transcervical electro-resection by hysteroscopy is a minimally invasive,safe,and effective method for submucous uterine myoma.Preoperative preparation,strict indication criteria,and intraoperative monitor are three key points to avoid operation-related complications.
