Comparision Of Retroperitoneoscopy And Open Parapelvic Cyst Unroofing

Objective：Combined with clinical data,review and consult the date of parapelvic cyst,to analyse and compare the clinical efficacy of retroperitoneoscopy paraplevic cystuprooting and open paraplevic cyst uprooting.Methods: The clinical data of80cases of patients of parapelvic cyst were analyzedretrospectively at the dept of urology of the affiliated provincial hospital of anhuimedical university between march2001and april2011.All patients of80cases wereperformed surgical treatment.And all of the cyst wall that cut during operation were sentto pathological examination.All cases were followed up on time. And divide them intotwo groups:38cases performed retroperitoneoscopy uprooting and42cases with openuprooting. On the one hand analyse and compare preoperative parameters of twogroups，on the other hand record the operation time,hemorrhage,postoperative recovery,analgesic, hospitalization，complications and the recurrence rate of two groups, usestatistical methods to compare and analysis.Results:1The operation of all of the patients are successful.During operation all of thepatients did not appear serious complications such as hemorrhoea.None of the group ofretroperitoneoscopy had translated to open operation.one case had damaged renal pelvisbecause of the deep location of the cyst，and cause lacerated wound of the renalpelvis.After given suture and repair and placed Ureteral stent drainage tube,it’s healgood.2The mean operating time of the group of retroperitoneoscopy were （61.3±11.4）minutes. There was statistical difference between the group of open which meanoperating time were（76.8±16.7） minutes (P<0.05).The mean bleeding volume during operation, analgesic，postoperative recovery time，postoperative hospital stays betweenretroperitoneoscopy group and open group were （60.8±12.5） ml and （290.±90.3）(P<0.05);15/38and40/42(P<0.05);（18.0±2.5）hours and（80.5±15.4）hours(P<0.05)；（5.5±1.2）days and （11.3±1.6）days（P＜0.05)，The retroperitoneoscopygroup have clearly advantages.3The retroperitoneoscopy group had no complications after operation.And the opengroup：one patient had transferred to ICU because of cardiorespiratory failure；onepatient produced stress ulcer；Fat liquefaction occured in two patients.The incidence rateof two groups were5.26%and7.14%，but it has no statistical significance.4The time of postoperative follow-up is12~24months，including all of the patients，The clinical symptoms of two groups all have improved，and the renal function wereall nomal.There were two cases and three cases recurrence between two groups.Therecurrence rate were respectively5.26%and7.14%，and it has no statistical significanceConclusions:1Open paraplevic cyst uprooting is a mature technology.It is safe and feasible.It candeal with other lesions of kidney.But the wound is big，the operation time is longer，thepostoperative recovery of patients is slower，and the hospitalization is longer.2Retroperitoneoscopy paraplevic cyst uprooting is safe and feasible，and curativeeffect is reliable.Compared with open surgery，it has advantages of small trauma, quickrecovery and fewer hospitalization.But it need high technical requirements. With theincrease of technology of diagnosis and treatment，it will be the ideal treatment ofparaplevic cyst.
