Table 1 [5]

  1. According to the classification system adopted in this study (Fig. 1):
  2. a Patients 2, 7, and 20 had testes that were completely separated from the epididymis (Figs. 3a, 5a, and 6b, malformation type B4).
  3. b Patient 8 had an epididymis attached at the caudal end only (Fig. 5b, malformation type B3), while patients 9, 10, and 11 had an epididymis attached at the caput and the cauda (detached corpus, Figs. 4a, 7, and 8, malformation type B1). However, patient 11 had a congenital diaphragm
  4. c 3 Patients had a congenitally absent proximal part of the left vas deferens (proximal aplasia) (patients 13, 14, and 15; Figs. 10 and 11, Table 1), and we previously reported a case of a congenitally absent distal part of the right vas deferens5!!
  5. d We recommend adding this missing anomaly and modifying the classification system of the vas deferens (Table 1) [5]
