RESUMO
BACKGROUND: Pediatric urolithiasis has been increasing at rate of 4-10 % annually in the United States, most notably within adolescents and females. A significant number of patients will require surgical management of their stones. Primary ureteroscopy (URS) affords the opportunity to treat stones under a single anesthetic with lower re-treatment rates or anatomical and stone characteristic limitations compared to shockwave lithotripsy. Previous studies evaluating primary URS have been largely underpowered, are limited by stone location, and/or are not representative of the stone population in the United States. OBJECTIVES: Primary study outcomes were the success of primary URS and patient characteristics associated with success. Secondary outcomes were the stone-free rate (SFR), 30-day emergency department (ED) visits, 30-day readmissions, and complications. METHODS: We performed a retrospective cohort study of patients less than 18 years of age from 2011 to 2023 who underwent primary URS. Patients were excluded if a ureteral stent was placed prior to URS or diagnostic URS was performed. A successful primary URS was considered if access to the ureter was obtained and treatment of the stone(s) completed. In failed primary URS, a ureteral stent was placed for staged management. RESULTS: A total of 196 patients were included and primary URS was performed or attempted on 224 renal units. The median age was 15.8 (IQR 13.4-16.9) years and median follow up 8.4 (IQR 1.1-24.6) months. The success rate of primary URS was 79 %. No significant characteristics were appreciated for successful primary URS based on: overall age, <14 vs > 14 years of age, sex, body mass index, history of stones, history of endourologic procedures, preoperative alpha blockade, location of stone(s), multiple stones, type of URS, or acute treatment. In successful primary URS, the SFR was 88 % with stone size (p = 0.0001) the only predictor of having residual stones. The 30-day ED rate was 21.4 %, 30-day unplanned readmission rate was 12.5 %, and complication rate was 7.5 %. No long-term complications were appreciated. DISCUSSION: Our success of primary URS compares favorably to previously published literature. Our SFR rate, 30-day ED visits, 30-day unplanned readmission, and complication rates are similar to other studies. Limitations of the study are its retrospective design, selection bias, and intermediate follow-up. CONCLUSIONS: Primary URS can be completed safely in the majority of pediatric patients without any patient characteristics associated with success. We advocate for primary URS when possible due to the excellent SFR and potential of treating stones under a single anesthetic.
RESUMO
BACKGROUND: Listening to preferred music can provide distraction and reduce the feeling of pain and negative emotions associated with an uncomfortable experience. Several studies have examined how music can reduce pain and anxiety related to urological procedures that are not typically performed under anesthesia, such as cystoscopy, cystoscopy with stent pull, and urodynamic studies. To our knowledge, no studies have been done to examine the effect of listening to preferred music generalized across a variety of these procedures. Therefore, we looked to combine multiple factors from prior studies to determine if listening to music of a patient's choice would decrease pain during various outpatient clinic urological procedures, and to examine differences between men and women. METHODS: This was a single investigator series randomized controlled trial with 91 subjects in an academic outpatient urology clinic. After applying exclusion criteria, eligible patients were randomized to a music group or non-music group via coin flip. Fifty-three patients were in the music group (16 men, 37 women) and 38 patients were in the non-music group (16 men, 22 women). Subjects in the music group selected a song to play during the procedure, which was stopped at the conclusion of the procedure. Pre- and post-procedure Visual Analog Pain Scale were completed by the subjects of each group and subsequently analyzed. Where appropriate either Pearson's Chi-Square or Independent-Sample t-test were used to compare the groups as well as randomized-repeated analysis of variance (ANOVA). RESULTS: For men, pain scores worsened in both groups, however the music group experienced a statistically significant increase in pain (mean change =1.0, P=0.05), while the non-music group only clinically worsened (mean change =0.38, P=0.459). For women, the music group noticed an improvement in the pain score (mean change =-0.14, P=0.590), while the non-music group significantly worsened (mean change =1.14, P=0.008). CONCLUSIONS: Women who listened to music of their choosing experienced significant improvement in overall perceived pain compared to women who did not listen to music. Women may benefit from music as a novel tool to alleviate pain during outpatient clinic urological procedures.
