Preoperative imaging contributes to pathologically complete resection of the urachal remnant by determining an appropriate surgical approach without unnecessary and excessive surgical invasion: a retrospective study

Table 2 UR continued toward the bladder apex by preoperative imaging

Approach	TU: 3 cases	LATU: 7 cases	p value
Patients’ background
Age (year)*	1 (0.5–1.5)	11 (8.5–12)	0.02
Sex (male), n (%)	2 (67%)	5 (71%)	> 0.99
Surgical outcomes
Operation time (min)*	59 (56–70)	131 (106.5–140.5)	0.02
Hospitalization (postoperative day)*	3 (3-3.5)	4 (3–4)	0.8
Balloon (postoperative day)*	3 (2-2.5)	2 (2–3)	0.7
Complications, n (%)	0 (0)	0 (0)	> 0.99

All cases were initially performed by TU approach (10 cases)
Three cases were completed by only TU approach, but seven cases required adding laparoscopic procedure, i.e. LATU approach was needed.
UR Urachal remnant; TU Trans-umbilical; LATU Laparoscopic-assisted trans-umbilical
*, Median (interquartile range)
Fisher’s exact test was used for discrete valuable. Wilcoxon Signed Rank test was used for continuous variable.
