Urological and intestinal functional outcomes of sacrococcygeal teratoma following surgery

Surgery for sacrococcygeal teratoma (SCT) in neonatal period may result in functional problems of micturation and defecation caused by pelvic nerve dam - age. We aimed to evaluate long term outcome of patients with SCT in terms of bladder dynamics. To evaluate the postoperative urological outcome related with SCT excision, urodynamic study, ultrasonographic and scintigraphic ex - aminations were performed. The families are asked about the micturition and defecation paterns. Twenty-one patients (eight male, thirteen female) underwent SCT excision between 2006 and 2013 and seventeen (six male, eleven female) are regarded eligible for long term evaluation. Incidence of constipation was 9.4%, encopresis 9.4% and urinary incontinence 4.7%. Two patients had a his - tory of urinary tract infection without reflux on voiding cystourethrography or renal scarring on renal cortical scintigraphy. Three patients had increased post - voiding residual urine of 25 to 35 mL while four had increased bladder capacity. Meticulous surgical technique for excision of SCT in newborns may avoid sig - nificant urinary and defecation problems subsequently.
