Abstract:
Objective To analyze the feasibility and safety in application of resectoscope combined with laparoscopy in the operation treatment of paraganglioma of urinary bladder.Methods 7 cases patients with paraganglioma of urinary bladder treated in our hospital from November 2014 to August 2018 were analyzed retrospectively.There were 5 males and 2 females,average age of 31.1 years (22-37 years),average body mass index was 22.3 kg/m2 (18.3-22.5 kg/m2).All the 7 cases patients complained of dizziness and palpitation after urination,average basal systolic blood pressure was 111.8 mmHg (97-124 mmHg),the average fluctuation of systolic blood pressure before and after urination was 64.9 mmHg(28-91 mmHg),the CT and cystoscopy prompt bladder tumor,the average diameter was 2.7 cm(2.1-3.5 cm).The average of plasma norepinephrine was 706.3 pg/ml(330-997 pg/ml);the average of plasma dopamine was 101.1 pg/ml(44-145 pg/ml);the average of 24h urinary vanilmandelic acid was 13.4 mg/24h (10.3-16.1 mg/24h).All the patients has controlled the blood pressure and dilate the blood vessels with phenoxybenzamine hydrochloride,accepted the operation of resectoscope combined with laparoscopy partial cystectomy and bladder sutura per abdomen after ample dilatancy.The patients had lithotomy position with trendelenburg,preparation of gas peritoneal cavity by transabdominal,inside the resectoscope by transurethral at the same time,mutilated bladder mucosa beside 1cm at the edge of the tumor,and cut full thickness bladder wall,take the extraperitional fat as the standard procedure;we could see the cutting edge clear at this time by laparoscopy,cut off the pelvic peritoneum,extraperitional fat and the tumor.The sample placed in bladder,close the bladder with absorbable or barbed wires,take out the sample by resectoscope.Results All the 7 cases patients operation was successfully completed,no cases has been transfered to open.The average time of operation is 85.3 min(65-100 min),the average amount of bleeding is 27.9 ml(10-50 ml).The average fluctuation of systolic blood pressure is 8.7 mmHg(6-15 mmHg).Bladder washout was stopped 24h after operation,catheter was removed 1 weeks after operation.There is no obvious complications occurred.The average hospital stay is 3.7 days (3-5 days).The average pain score of 4 cases 4h after operation is 3.8 (2-5),reevaluation 24h after operation is 2.3 (1-4).The average follow-up time is 7.9 months(2-15 months).All the 7 cases patients clinical symptoms disappeared,there is no fluctuation of systolic blood pressure before and after urination,there is no recurrence of the tumor.Conclusions To the paraganglioma of urinary bladder in fundus of bladder or anterior wall of bladder,we can accurate resection tumor by resectoscope combined with laparoscopy,reduce blood pressure fluctuations,reduce the surgical trauma and the distress of patients.It is a safety and effective minimally invasive surgery.
