“…It was observed that even though the ureteral length was in a range among countries it could be influenced by the sample size we have selected. In the above studies also there is no significant difference between right and left ureterals [7]. In Sri Lanka commonly used ureteralic stent is 26cm.…”

Purpose: The ureteral stent is an essential in various urological procedures. Therefore, choosing an ideal ureteral stent is central to minimizing the incidence of stent related complications. This study aim was to identify the average length of ureteral in adult population as it would help to opt for optimal stenting according to the variability of age and gender. Materials and methods: It was a descriptive cross-sectional study at Teaching Hospital Jaffna and underwent to analysis the average length of ureteral among adults based on their CT urogram. This study was approved (Reg.No:S01/07/2021) on 30 September 2021 by the Ethics Review Committee of Teaching Hospital Jaffna and the patient informed written consent was received. A total number of 69 patients had been ordered for computed tomography urogram consecutively in last 4 months from 1st October 2021to 31st January 2022. All ureterals with pathological conditions were excluded from this study. The actual and linear lengths were calculated by using the Radiant DICOM viewer 3.2.3. Results: The gender distribution was men 69.6% and women 30.4%. Fifty seven (49.6%) were right ureterals and fifty eight (50.4%) were left ureterals. The average length of ureteral right and left were 23.03 (±3.15) cm and 23.48 (±3.17) cm respectively. The average length of right ureteral in male was 23.03 (±2.85) cm and left was 23.64 (±3.16) cm while it was estimated in female right 23.03 (±3.82) cm and left 22.98 (±3.26) cm. The multiple linear regressions showed that there is a no linear relationship between the ureteral length and age or gender. Conclusion: The average actual length of ureteral of Jaffna adult population is 23.03 (±3.15) cm in right and 23.48 (±3.17) cm in left. The median ureteral length is 23.26 (±3.15) cm. Therefore, it is prudent to use 24cm ureteral stent to Sri Lankan population.

“…In above Kalubowila Teaching hospital study they concluded as for females the average actual length of right ureteral was 21.9cm and for left was 22.9cm. For males average actual length of right ureteral was 22.3cm and for left was 22.4cm [7].…”

“…Therefore, in this RCT, the length of the ureteral stent was chosen according to the patient’s body height; however, the stent in ten patients (8.8%) was located in an unintended position on POD 14. Other methods have also been reported, such as using computed tomography [ 22 ] or plain radiography [ 23 ]. However, there is no reliable method for determining ureteral stent length.…”

Purpose To evaluate the correlation between the position of a ureteral stent and stent-related symptoms in a single-center randomized study. Methods A total of 113 patients who required ureteral stent placement after lithotripsy were randomized at a 1:1 ratio into groups with stents crossing and not crossing the bladder midline. The ureteral stent remained in place until postoperative day 14, when we obtained each patient’s International Prostate Symptom Score (IPSS), overactive bladder symptom score (OABSS), and visual analog scale (VAS) pain score. Results Comparing changes from baseline IPSS and OABSS scores between the two groups, the midline crossing group had a worse OABSS total score than the not crossing group (3.0 ± 2.8 vs. 2.0 ± 3.3; p = 0.032). There was no significant difference between the crossing and not crossing groups in IPSS total score (6.8 ± 7.6 vs. 5.1 ± 8.5; p = 0.14). The OABSS urgency mean score was significantly lower in the not crossing than in the crossing group (1.1 ± 1.8 vs. 1.6 ± 1.8; p = 0.042). However, there was no significant difference between groups for remaining items of the IPSS and OABSS and the mean VAS total pain score (1.9 ± 2.7 vs. 1.2 ± 1.9; p = 0.14). Conclusion A ureteral stent that crossed the bladder midline led to worse urinary symptoms. Choosing the appropriate stent length for each patient is important to minimize stent-related symptoms.

“…A review of the available literature demonstrates that there are a number of available methods with which to estimate ureteric length and, subsequently, choose the appropriate stent. Previously described methods include use of patient height [ 8 ], direct measurement using a guidewire [ 9 ] or endocatheter ruler [ 8 ], measurement of ureteral length from intravenous pyelogram (IVP) [ 10 ], computed tomography (CT), [ 11 , 12 ] or kidney ureter bladder (KUB) x-ray [ 13 ], or simply empiricism based on surgeon experience. Despite all the described methods, we have little understanding as to which method endourologists are using.…”

Introduction Ureteral double-J stent length is an important factor affecting stent-related symptoms. Multiple techniques exist to determine ideal stent length for a given patient, however, little is known about what techniques urologists rely on. Our objective was to identify how urologists determine optimal stent length. Material and methods An online survey was e-mailed in 2019 to all members of the Endourology Society. The survey sought to assess what methods are commonly used to determine choice of stent length, along with frequency of stent placement post ureteroscopy, duration of stenting, availability of different stent lengths and the use of stent tether. Results 301 urologists (15.1%) responded to our survey. Following ureteroscopy, 84.5% of respondents would stent at least 50% of the time. Following uncomplicated ureteroscopy, most respondents (52.0%) would leave a stent for 2–7 days. Patient height was most commonly ranked first as the method of choice in determining stent length (47.0%), followed by estimation based on experience only (20.6%) and intra-operative direct measurement of ureteric length (19.1%). Most respondents utilized multiple methods in determination of optimal stent length. Most respondents (66.5%) were interested in a simple intra-operative technique utilizing a special ureteral catheter that would help choose the most appropriate stent length. Conclusions Post-ureteroscopy stent insertion is common and patient height is the most common method of choice used in determining optimal stent length. Most respondents were interested in using a simple, novel ureteral catheter device that would allow them to more accurately select optimal stent length.
