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 discuss the clinical efficacy of transurethral electroresection in the treatment of ureteral orifice tumors. Methods A total of 65 cases of ureteral orifice tumor were treated with transurethral electroresection and chemotherapy.Results The operation time was 5~90 min(mean,35 min),and the intraoperative blood loss was 5~100 ml(mean,50 ml).No blood transfusion was required.No fatal case was encountered.Out of the 65 cases,there were 53 cases of transitional cell carcinoma(grade Ⅰ,43 cases;grade Ⅱ,10 cases) and 12 cases of papilloma.The 65 cases were followed for 6~24 months(mean,15 months).Postoperative urethral stricture happened in 4 cases,which were cured by dilation of the urethra.Recurrence of tumor at the trigone and lateral wall of the bladder occurred in 5 cases,which were given a re-operation of transurethral electroresection and chemotherapy and were followed for 10~20 months(mean,15 months) without recurrence.Conclusions Transurethral electroresection of ureteral orifice tumors gives satisfactory effects and should be further recommended.
ABSTRACT
Objective To compare the clinical effects between hysteroscopic electroresection and open hysterectomy in the treatment of intrauterine benign diseases. Methods A total of 58 women with intrauterine benign received hysteroscopic electroresection (hysteroscopic group) and 60 women underwent open total hysterectomy (control group). The operating time, hospital stay, postoperative recovery and cure rates were compared between the two groups, respectively. Results The operating time was 68.4?20.6 min in control group and 55.2?19.7 min in hysteroscopic group ( t=-3.555, P =0.000). The postoperative hospital stay was 7.2?1.8 d and 4.5?1.5 d in control and hysteroscopic group, respectively ( t=-8.836, P =0.000). The time to resume regular work was 64.4?25.3 d in control group and 37.2?7.8 d in hysteroscopic group ( t=-7.835, P =0.000). The cure rates in control and hysteroscopic group were 100% (60/60) and 94.7% (54/57), respectively ( ? 2 =1.477, P =0.224). Conclusions Hysteroscopic electroresection gives good short-term therapeutic effects and quick postoperative recovery. It may replace hysterectomy in part of patients with intrauterine benign diseases.
ABSTRACT
Objective To compare the effects between dilation and curettage (D&C) and hysteroscopic electroresection (HE) in the management of endometrial polyps. Methods Entered into the study there were 86 patients with endometrial polyps, 32 of them were treated by D&C (Group D&C) and 54 by HE (Group HE). The operation time, pre- and post- operative complications, and recurrence of 2 groups were compared. Results Of the Group D&C and Group HE, the operation time were (8.5?4.2) min and (9.0?3.1) min, without statistically significant differences (t=0.632, P=0.529), while the recurrence numbers and recurrence time of the 2 groups were 9 (36.0%) and 3 (7.5%) cases, (5.3?3.5) months and (11.2?4.8) months, respectively, with significant differences (?2=6.516, P= 0.011; t=6.058, P=0.000). Conclusions Compared with D&C, HE is characterized by lower recurrence rate and longer recurrence time.
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.
ABSTRACT
Objective To investigate the efficacy of transurethral electroresection combined with intravesical irrigation with epirubicin for cystitis glandularis.Methods From January 2000 to January 2006,130 patients with cystitis glandularis were treated with transurethral electroresection.The whole depth of diseased mucosa and adjacent normal mucosal tissues(1 cm away)were resected.One week after the operation,intravesical irrigation with epirubicin were carried out(50 mg per time,once a week for 8 weeks,and then once a month for 2 years).Results Five of the patients developed urethral stenosis after the electroresection,and were cured by dilating the urethra at a regular interval.No complications occurred in the other patients.Bladder symptoms disappeared in 98 patients;23 cases had urinary symptoms occasionally,but cystoscopy showed normal vesical mucosa.Nine of the patients had recurrent cystitis,5 of which showed non-irrigation-induced hematuria 6-12 months after the operation,and 4 were found during regular re-examination by cystoscopy.Transurethral electroresection was performed again on these 9 patients,after they were diagnosed by biopsy;and then intravesical irrigation with hydroxycamptothecin(20 mg per time)were given.They were followed up for 12 months,during which no one had recurrence.Conclusions Transurethral electroresection combined with intravesical chemotherapy is effective for cystitis glandularis.The method is worth being widely used.
