Abstract:
Objective To evaluate the feasibility and clinical efficacy of laparoscopic nephron-sparing surgery without renal wound suturing.Methods From December 2012 to February 2014,9 patients (4 male,5 female) with renal tumor underwent laparoscopic nephron-sparing surgery without suturing in our hospital.The mean age in those patients was 56 years (range 42-72 years).The mass size ranged from 1.1to 3.8 cm (mean 2.4 cm).The location of tumor included 2 in left kidney,7 in right kidney.Meanwhile,6 tumors were found in the middle part of kidney,2 tumors were demonstrated in the lower part of kidney,and 1 tumor located in the upper part of kidney.The imaging examination confirmed that all tumors protruded the renal surface and infiltrated into the renal parenchyma about 0.1-1.2 cm,which could be defined as the peripheral renal tumor without the invasion of collective system.The retroperitoneal approach was used in all patients with 3 trocars.During the operation,the renal artery was exposed and fats surrounding or on the surface of the tumor were resected.The renal artery was occluded.Tumor excision was then performed using scissors.An incision was made at the point 0.5 cm away from the margin of the tumor,extending deeply to completely cut the tumor.Meanwhile,bleeding was controlled with bipolar diathermy.Then,the clamping of the renal artery was removed and the retroperitoneal pressure was reduced in order to check the site of bleeding.If the bleeding occurred severely,the kidney wound was sutured with 2-0 absorbable sutures.Otherwise,the coagulative glue was sprayed on the wound surface.Results In all the patients,the procedures were done without conversion to open surgeries.The renal wound suturing appeared in one case because the tumor infiltrated into the deep of the kidney and the bleeding could not be completely controlled by bipolar diathermy.Eight of 9 cases were successfully performed without suturing.The mean time of renal artery occlusion was 8 min (range 3-18 min).In our patients,the mean operation time was 120 min (90-180 min),and the mean blood loss was 60 ml (10-200 ml).None of the patients received blood transfusion during the surgery.The mean postoperative hospital stay was 7 days (5-9 days).No complications,such as urine leakage,bleeding occurred after the operation.All the patients were followed up with no recurrence of tumor.Conclusions Laparoscopic nephron-sparing surgery without renal wound suturing is feasible and safe for patients with the small and the depth of infiltration less than 0.5 cm tumor in the kidney.
