“…Several methods have been described to determine the appropriate stent length: (1) intraoperative direct measurement of the ureter itself using a guidewire [12] or an endocatheter ruler [13,14] , (2) measurement of the distance from the ureteropelvic to the ureterovesical junction with intravenous urography (IVU) [15,16] , and (3) estimation from a formula based on the patient's height [9] .…”

Objective: We conducted this study to determine the ideal stent length according to body height, as data are limited. Patients and Methods: A total of 408 patients undergoing ureteroscopic lithotripsy and stent insertion (22, 24 or 26 cm) were enrolled. The appropriateness of the stent length was determined according to the plain films and was further compared among patients with different body heights and stent lengths. Results: In patients <160 cm, the use of a 22-cm stent was significantly more appropriate than a 24- or 26-cm stent (86.5, 51.9 and 46.4%). In patients between 160 and 175 cm, a 22- or 24-cm stent was significantly more appropriate than a 26-cm stent (79.2, 66.7 and 46.3%), while the difference between the use of a 22- and 24-cm stent was not significant. In patients >175 cm, a 24- or 26-cm stent might be more appropriate. Conclusions: Body heights can predict the ideal stent length. Based on a Chinese population, a 22-cm stent length is more appropriate for those <175 cm. A longer, 24- or 26-cm stent may be suitable for those >175 cm.

“…It seems to be a practical and reasonable method, and a few investigators have dealt with this issue and support this idea [9,10] . However, the existent formula or method for choosing the appropriate stent length according to body height is limited and scarce.…”

“…Hruby et al (2) in a similar study used endoscopy and radioscopy to measure ureteral length and found a weak correlation with height, xiphoid appendix-pubis distance and (8) found no correlations between height and ureteral length. In view of these facts, this study reaffirms previous works regarding the lack of correlation between different segments of the human body and the ureteral length, making impossible the proposal of a predictive formula.…”

“…In the era of minimally invasive surgeries, the previous knowledge of ureteral length allows a correct planning of a reconstructive surgery or ureteral reimplantation, reducing costs, without the need of invasive subsidiary exams, such as cystoscopy or radiological profiles (for example, intravenous pyelography or computerized tomography). The correct choice of the length of a double-J catheter reduces symptoms and morbidity (2-7) and one of the determinants is the catheter length (3,8,9). A very long catheter can cause irritative symptoms, while a short one allows migration (3,8,10,11).…”
