RESUMO
INTRODUCTION: Percutaneous nephrolithotripsy (PCNL) is a minimally invasive procedure for treating large and complex kidney stones, often resulting in significant post-operative pain and increased opioid use. This study aims to compare pain scores between patients undergoing PCNL who did and did not receive a preoperative single-shot thoracic paravertebral block (PVB) at the post-anesthesia care unit (PACU) as the primary outcome. Secondary outcomes were patient-controlled analgesia (PCA) usage on post-operative day 1 (POD 1), total opioid consumption on PACU and POD 1, and post-operative nausea and vomiting (PONV). METHODS: A retrospective cohort study was conducted on the medical records of 341 patients who underwent PCNL from July 2014 to April 2016 in a single major academic center. PVB was administered at thoracic levels T7-9 using a volume of 20 cc of bupivacaine, ranging from 0.25% to 0.5%, to achieve the desired analgesic effect. RESULTS: After excluding 34 patients, the study included 123 in the no block (NB) group and 149 in the regional anesthesia (RA) group. There were no differences in demographics, including age, sex, weight and height, BMI, and indication for PCNL. The results revealed that the RA group experienced a statistically significant reduction in PCA usage in both crude and adjusted models (adjusted logistic regression analysis: OR = 0.19, 95% CI = 0.05-0.60; p = 0.008). However, there were no significant changes in total opioid consumption, pain scores, or incidents of PONV. CONCLUSION: The retrospective analysis did not reveal any discernible advantage in pain management associated with the use of PVB for post-PCNL analgesia, except for reducing the percentage of PCA narcotics used. Future investigations with larger sample sizes and meticulous control for surgical indications and complexity are imperative to accurately assess the efficacy of this block in the context of post-PCNL surgery.
RESUMO
PURPOSE: The purpose of this study was to determine the effectiveness of television (TV) streaming on hearing aid user performance and satisfaction in quiet and in noise. METHOD: Twenty experienced hearing aid users were evaluated in quiet and in noise (5 dB SNR) under three hearing aid conditions: hearing aids, streaming with hearing aid microphones attenuated by 6 dB, and streaming with hearing aid microphones muted. The audiovisual Connected Speech Test served as the signal, and the ipsilateral competing message from the Synthetic Sentence Identification-Ipsilateral Competing Message (SSI-ICM) served as the noise. Measures of speech understanding, satisfaction with sound quality and clarity, and preference were obtained. RESULTS: Speech understanding was significantly better in quiet than in noise, and streaming improved performance in noise when the hearing aid microphones were muted. Sound quality satisfaction was significantly better in quiet than in noise but was not impacted significantly by the hearing aid settings. Speech clarity satisfaction was significantly better in quiet than in noise, and streaming improved satisfaction in noise when the hearing aid microphones were muted. More participants preferred streaming with the microphones muted in quiet, in noise, and overall; however, results did not reach statistical significance. CONCLUSIONS: Hearing aid users did not benefit from TV streaming with the microphones attenuated or muted when listening in quiet. TV streaming was more beneficial to hearing aid users when listening in noise with the microphones muted. Hearing aid users should be counseled on the impact of the hearing aid microphone settings when using a TV streamer, particularly in noise.
RESUMO
BACKGROUND: Congenital renal anomalies are rare but may be associated with obstruction of the ureteropelvic junction. Given the rarity of simultaneous ureteropelvic junction obstruction [UPJO] and renal anomalies in the adult population, there is limited literature on approaching these patients. We report our experience with robotic assisted laparoscopic pyeloplasty for UPJO repair in this subset of patients. METHODS: Data on adult patients with simultaneous congenital renal abnormalities and UPJO who underwent robotic assisted laparoscopic pyeloplasty between 2008 and 2020 was reviewed. Pre-operative data, intraoperative parameters as well as post-operative data including symptom resolution and radiologic findings were recorded. RESULTS: Ten patients, 4 female and 6 males, with a mean age of 47 years were identified as having simultaneous congenital renal abnormalities and UPJO. Anomalies identified were horseshoe kidney in four patients, duplex kidney with obstruction of one moiety in two patients, malrotated kidney in two patients, and pelvic kidney in two patients. Eight out of ten were symptomatic at presentation with flank pain being the most common symptom. Eight patients underwent robotic pyeloplasty via the dismembered technique, while two underwent robotic Y-V pyeloplasty. With a mean follow up time of 13 months, 8/9 (88%) symptomatic patients enjoyed symptom resolution. Post-op renogram was available for nine patients and showed resolution of obstruction in all patients (100%). One patient developed a urine leak which was managed successfully with drainage. CONCLUSIONS: Robotic assisted laparoscopic pyeloplasty is a safe, feasible and effective surgical approach in management of adult patients with concomitant UPJO and renal anomalies.

OBJECTIVE: To evaluate the outcome of robotic-assisted laparoscopic pyeloplasty (RAP) in symptomatic patients with ureteropelvic junction obstruction (UPJO) versus patients who were incidentally found to have UPJO. METHODS: We retrospectively reviewed the records of 141 patients who underwent RAP at Massachusetts General Hospital between 2008 and 2020. Patients were categorized into symptomatic group and asymptomatic group. We compared patient demographics as well as preoperative and postoperative symptoms and functional renal scans. RESULTS: The study population included 108 patients in the symptomatic group and 33 patients in the asymptomatic group. Mean age was 46 ± 17 years with average follow-up time of 12 ± 18 months. Asymptomatic patients had significantly higher rate of definite obstruction (80% versus 70%) and equivocal obstruction (10% versus 0.9%) on preop renogram (P: 0.001). There was no significant difference in the preop split renal function in symptomatic versus asymptomatic group (39 ± 13 versus 36 ± 13 P: 0.3). Following RAP, 91% of symptomatic patients achieved symptom resolution, while four asymptomatic patients (12%) developed new symptoms postoperatively. Compared to preoperative renogram, RAP resulted in improvement in renogram indices in 61% of symptomatic versus 75% of asymptomatic patients (P: 0.2). CONCLUSION: Although asymptomatic patients had worse obstructive indices on renogram, both symptomatic and asymptomatic groups had comparable improvement in renal function following robotic pyeloplasty. RAP is a safe and efficacious minimally invasive option to offer symptom resolution in symptomatic patients and improve obstruction in both symptomatic and asymptomatic patients with UPJO.
