Summary
Introduction/Background
Reconstructive and ablative urologic techniques require special technical mastery,
especially the intracorporeal suturing.
Objective
To report the subjective evaluation of a versatile ex-vivo model aimed to practice laparoscopic ureteric reconstructive techniques (LURT) on
box-trainer.
Study design
The model is a continuous portion of porcine urinary bladder (“dilated pelvis”), the
vesico-ureteral joint (“stenosis”) and healthy ureter. All 127 participants (n = 119
urologists and n = 8 paediatric surgeons) performed on the model laparoscopic Anderson-Hynes
dismembered pyeloplasty, and then, in the animal model, different LURT procedures
(ureteroneocystostomy, ureteric reimplantation and/or dismembered pyeloplasty). The
model was subjectively evaluated (face and content validity), through a 12 items questionnaire,
based on a Likert scale (1–5 points) and a global question (1–10 points).
Results
The total mean rating for 11/12 items was very high (>4points). Only one was rated
under 3 points. The overall total mean rating from 1 to 10 points was very high (9.19 ± 0.82
points). In 10/12 items, expert's feedback (content validity) prevailed over non-experts
(face validity).
Discussion/conclusion

Graphical AbstractA) LURT organic model arranged on an angled platform (±45°) for the practice of dismembered
pyeloplasty. Note the simple assembly of the model inside the physical simulator is
shown. B) Suture line correctly performed by an expert. C) An incorrect apposition
of the edges can be seen. Besides, some fatty tissue is incorrectly included in the
suture line.
