Initial experience of horseshoe kidney treated with transperitoneal laparoscopic plastic surgery / 中华泌尿外科杂志

ABSTRACT

ObjectiveTo investigate the feasibility,technique and clinical effect of applying laparoscopic plastic surgery in the treatment of horseshoe kidney.Methods Eleven patients with horseshoe kidney were admitted from Mar.2006 to Mar.2011.There were 5 males and 6 females with mean age of 27years (14 to 46 years).Clinical manifestations included lower-back pain in 8 cases,lower-back pain and hematuria in 2 cases,lower-back pain and fever in 1 case.There were 6 cases accompanied with kidney calculi.All the cases with calculus were in left kidney and there was 1 case with multiple calculi.There were 11 cases accompanied with left hydronephrosis.Of which,there were moderate hydronephrosis in 6 cases,severe hydronephrosis in 5 cases.There were 3 cases accompanied with mild right hydronephrosis.There were 2 patients with renal insufficiency,1 patient with urinary tract infection.The surgery procedures included laparoscopic isthmectomy and plastic surgery in 3 cases,isthmectomy and plastic surgery and pelviolithotomy in 6 cases,isthmectomy and vascular compression release in 2 cases.ResultsAll patients had successful surgeries with the mean operative time of 145 min (95 - 190 min).The average blood loss was 250 ml ( 100 -400 ml).Average postoperative hospital stay was 10 d (7 - 15 d).One patient suffered from urinary leakage after surgery and recovered after anti-inflammatory therapy and local drainage.One patient suffered from secondary hemorrhage controlled with DSA.All the patients were followed up with a mean of 17 months (6 -28 months).In 6 cases with moderate hydronephrosis,5 patients recovered to mild hydronephrosis and 1 case improved from preoperative renal hydronephrosis 3.5 cm to postoperative 3.0 cm.In 5 cases with severe hydronephrosis,3 patients improved to moderate hydronephrosis,2 patients to mild hydronephrosis.One patient with kidney stone had 0.4 cm residual stone.Three patients complained of occasional mild backache.One patient suffered from hematuria and urinary tract infection,recovered after antiinflammatory therapy for 2 weeks.The remaining 6 patients were in good conditions during the follow-up.ConclusionTransperitoneal laparoscopic plastic surgery is able to deal with horseshoe kidney isthmus malformation and comorbidities,and is another alternative for the treatment of horseshoe kidney.
