Can Activities of Daily Living Predict Complications following Percutaneous Nephrolithotomy?

Effect of esketamine on the ED50 of propofol for successful insertion of ureteroscope in elderly male patients: a randomized controlled trial

BACKGROUND

Propofol is effective and used as a kind of routine anesthetics in procedure sedative anesthesia (PSA) for ureteroscopy. However, respiratory depression and unconscious physical activity always occur during propofol-based PSA, especially in elderly patients. Esketamine has sedative and analgesic effects but without risk of cardiorespiratory depression. The purpose of this study is to investigate whether esketamine can reduce the propofol median effective dose (ED50) for successful ureteroscope insertion in elderly male patients.

MATERIALS AND METHODS

49 elderly male patients undergoing elective rigid ureteroscopy were randomly divided into two groups: SK Group (0.25 mg/kg esketamine+propofol) and SF Group (0.1 µg/kg sufentanil+propofol). Patients in both two groups received propofol with initial bolus dose of 1.5 mg/kg after sufentanil or esketamine was administered intravenously. The effective dose of propofol was assessed by a modified Dixon's up-and-down method and then was adjusted with 0.1 mg/kg according to the previous patient response. Patients' response to ureteroscope insertion was classified as "movement" or "no movement". The primary outcome was the ED50 of propofol for successful ureteroscope insertion with esketamine or sufentanil. The secondary outcomes were the induction time, adverse events such as hemodynamic changes, hypoxemia and body movement were also measured.

RESULT

49 patients were enrolled and completed this study. The ED50 of propofol for successful ureteroscope insertion in SK Group was 1.356 ± 0.11 mg/kg, which was decreased compared with that in SF Group, 1.442 ± 0.08 mg/kg (P = 0.003). The induction time in SK Group was significantly shorter than in SF Group (P = 0.001). In SK Group, more stable hemodynamic variables were observed than in SF Group. The incidence of AEs between the two groups was not significantly different.

CONCLUSION

The ED50 of propofol with esketamine administration for ureteroscope insertion in elderly male patients is 1.356 ± 0.11 mg/kg, significantly decreased in comparsion with sufentanil.

Comparison of Robot-Assisted and Open Radical Cystectomy in Recovery of Patient-Reported and Performance-Related Measures of Independence: A Secondary Analysis of a Randomized Clinical Trial

IMPORTANCE

No data exist on time to recovery of patient-reported and performance-related measures of functional independence after radical cystectomy (open or robotic).

OBJECTIVE

To determine recovery of functional independence after radical cystectomy and whether robot-assisted radical cystectomy (RARC) is associated with any advantage over open procedures.

DESIGN, SETTING, AND PARTICIPANTS

Data for this secondary analysis from the RAZOR (Randomized Open vs Robotic Cystectomy) trial were used. RAZOR was a phase 3 multicenter noninferiority trial across 15 academic medical centers in the US from July 1, 2011, to November 18, 2014, with a median follow-up of 2 years. Participants included the per-protocol population (n = 302). Data were analyzed from February 1, 2017, to May 1, 2021.

INTERVENTIONS

Robot-assisted radical cystectomy or open radical cystectomy (ORC).

MAIN OUTCOMES AND MEASURES

Patient-reported (activities of daily living [ADL] and independent ADL [iADL]) and performance-related (hand grip strength [HGS] and Timed Up & Go walking test [TUGWT]) measures of independence were assessed. Patterns of postoperative recovery for the entire cohort and comparisons between RARC and ORC were performed. Exploratory analyses to assess measures of independence across diversion type and to determine whether baseline impairments were associated with 90-day complications or 1-year mortality were performed.

FINDINGS

Of the 302 patients included in the analysis (254 men [84.1%]; mean [SD] age at consent, 68.0 [9.7] years), 150 underwent RARC and 152 underwent ORC. Baseline characteristics were similar in both groups. For the entire cohort, ADL, iADL, and TUGWT recovered to baseline by 3 postoperative months, whereas HGS recovered by 6 months. There was no difference between RARC and ORC for ADL, iADL, TUGWT, or HGS scores at any time. Activities of daily living recovered 1 month after RARC (mean estimated score, 7.7 [95% CI, 7.3-8.0]) vs 3 months after ORC (mean estimated score, 7.5 [95% CI, 7.2-7.8]). Hand grip strength recovered by 3 months after RARC (mean estimated HGS, 29.0 [95% CI, 26.3-31.7] kg) vs 6 months after ORC (mean estimated HGS, 31.2 [95% CI, 28.8-34.2] kg). In the RARC group, 32 of 90 patients (35.6%) showed a recovery in HGS at 3 months vs 32 of 88 (36.4%) in the ORC group (P = .91), indicating a rejection of the primary study hypothesis for HGS. Independent ADL and TUGWT recovered in 3 months for both approaches. Hand grip strength showed earlier recovery in patients undergoing continent urinary diversion (mean HGS at 3 months, 31.3 [95% CI, 27.7-34.8] vs 33.9 [95% CI, 30.5-37.3] at baseline; P = .09) than noncontinent urinary diversion (mean HGS at 6 months, 27.4 [95% CI, 24.9-30.0] vs 29.5 [95% CI, 27.2-31.9] kg at baseline; P = .02), with no differences in other parameters. Baseline impairments in any parameter were not associated with 90-day complications or 1-year mortality.

CONCLUSIONS AND RELEVANCE

The results of this secondary analysis suggest that patients require 3 to 6 months to recover baseline levels after radical cystectomy irrespective of surgical approach. These data will be invaluable in patient counseling and preparation. Hand grip strength and ADL tended to recover to baseline earlier after RARC; however, there was no difference in the percentage of patients recovering when compared with ORC. Further study is needed to assess the clinical significance of these findings.

Utility of Frailty Assessment in Urologic Stone Surgery: A Review of the Literature

Introduction & Objective As life expectancy continues to rise, the prevalence of frailty is also increasing. The idea of frailty and its effect on the operative patient has been previously studied, but not regularly incorporated into routine practice. We present a review on frailty metrics in the literature, validated assessment methods, and simplified screening tools, to better predict and optimize patient outcomes. Methods An online Pubmed search was conducted by 3 authors (TA, TB, MM) for all frailty, frailty assessment, and pre-operative risk assessment. Only English publications were included in the analysis. Full text analysis was then conducted by all three authors to validate the data. Results An abundance of literature was found on frailty. Even though some methods are validated as very effective for assessing frailty, they may be time consuming and require a specialist. various quick screening methods are also present, many already validated, and should be utilized by urologist more regularly. Conclusions Multiple studies demonstrate the relationship between frailty and surgical patients' outcome. Many quick, office based, validated tools to screen for frailty are described, and should be incorporated into our practice in appropriate patients. Future research is now focused on the concept of "prehabilitation" to improve patient frailty status in the pre-operative setting, and consequently operative outcomes.

Frailty as predictor of complications in patients undergoing percutaneous nephrolithotomy (PCNL)

INTRODUCTION & OBJECTIVE

Surgical complications are difficult to predict, despite existing tools. Frailty phenotype has shown promise estimating postoperative risk among the elderly. We evaluate the use of frailty as a predictive tool on patients undergoing percutaneous renal surgery.

METHODS

Frailty was prospectively analyzed using the Hopkins Frailty Index, consisting of 5 components yielding an additive score: patients categorized not frail, intermediate, or severely frail. Primary outcomes were complications during admission and 30-day complication rate. Secondary outcomes included overall hospital length of stay (LOS) and discharge location.

RESULTS

A total of 100 patients recruited, of whom five excluded as they did not need the procedure. A total of 95 patients analyzed; 69, 10, and 16 patients were not frail, intermediate, and severely frail, respectively. There were no differences in blood loss, number of dilations, presence of a staghorn calculus, laterality, or location of dilation. Severely frail patients were likely to be older and have a higher American Society of Anesthesiologists score and Charlson comorbidity index. Patients of intermediate or severe frailty were more likely to exhibit postoperative fevers, bacteremia, sepsis, and require ICU admissions (P < 0.05). Frail patients had a longer LOS (P < 0.001) and tended to require skilled assistance when discharge (p < 0.0001).

CONCLUSIONS

Frailty assessment appears useful stratifying those at risk of extended hospitalization, septic complications, and need for assistance following percutaneous renal surgery. Risks of sepsis, bacteremia, and post-operative hemorrhage may be higher in frail individuals. Preoperative assessment of frailty phenotype may give insight into treatment decisions and represent a modifiable marker allowing future trials exploring the concept of "prehabilitation".

Anesthetic considerations for urologic surgeries

Urologic surgeries are widely performed, and the cases have increased owing to the fact that the elderly population is growing. The narrow and limited surgical space is a challenge in performing most urologic surgeries. Additionally, the elderly population is exposed to the risk of perioperative complications; therefore, a comprehensive understanding and approach are required to provide optimized anesthesia during surgery. We have searched the literature on anesthesia for urologic surgeries and summarized the anesthetic considerations for urologic surgeries.

Comprehensive geriatric assessment prediction of postoperative complications in gastrointestinal cancer patients: a meta-analysis

Background

Gastrointestinal cancer is an age-associated disease, and geriatric patients are mostly likely to suffer from postoperative complications. Some studies indicated that comprehensive geriatric assessment (CGA) could predict postoperative complications in gastrointestinal cancer patients. However, the evidence is mixed.

Objective

This study aimed to conduct a meta-analysis to identify the effectiveness of CGA for predicting postoperative complications in gastrointestinal cancer patients.

Methods

The Joanna Briggs Institute Library, Cochrane Library, PubMed, Embase, Web of Science, CINAHL Complete and four Chinese databases were searched for studies published up to March 2017. Two reviewers independently screened literature, extracted data and assessed the quality of included studies. RevMan5.3 was used for meta-analysis or only descriptive analysis.

Results

Six studies were included, with 1,037 participants in total. In all, 13 components of CGA were identified, among which comorbidity (Charlson Comorbidity Index [CCI] ≥3; odds ratio [OR]=1.31, 95% CI [1.06, 1.63], P=0.01), polypharmacy (≥5 drugs/day; OR=1.30, 95% CI [1.04, 1.61], P=0.02) and activities of daily living (ADL) dependency (OR=1.69, 95% CI [1.20, 2.38], P=0.003) were proven relevant to the prediction of postoperative complications. No conclusive relationship was established between instrumental activities of daily living (IADL) dependency (OR=1.18, 95% CI [0.73, 1.91], P=0.51), Mini-Mental State Examination (MMSE; OR=1.13, 95% CI [0.91, 1.41], P=0.27), potential malnutrition (OR=1.07, 95% CI [0.87, 1.31], P=0.54), malnutrition (OR=1.26, 95% CI [0.80, 1.99], P=0.32), Geriatric Depression Scale (GDS; OR=1.18, 95% CI [0.90, 1.55], P=0.24) and postoperative complications.

Conclusion

Comorbidity (CCI ≥3), polypharmacy (≥5 drugs/day) and ADL dependency were predictive factors for postoperative complications in gastrointestinal cancer patients; the results of other geriatric instruments were not conclusive, pointing to insufficient studies and requirement of more original investigations.

Research progress of percutaneous nephrolithotomy

Percutaneous nephrolithotomy (PCNL) is generally accepted as the gold standard treatment for the treatment of large kidney stones (> 2 cm). For nearly 40 years, with the continuous progress of technology and the constant updating of ideas, PCNL has made great progress. In this review, we discuss the current research progress, recent advancement and hot spot of the whole process of PCNL including anesthesia, position, puncture, dilation, lithotripsy approaches, perfusate, tube placement, hospitalization time, drug, treatment of residual stones, prognosis judgment and operation evaluation by summarizing the related research in this article.

Percutaneous nephrolithotomy: complications and how to deal with them

Percutaneous nephrolithotomy is a common surgical treatment for large and complex stones within the intrarenal collecting system. A wide variety of complications can result from this procedure, including bleeding, injury to surrounding structures, infection, positioning-related injuries, thromboembolic disease, and even death. Knowledge of the different types of complications can be useful in order to prevent, diagnose, and treat these problems if they occur. This review describes the diversity of complications with the goal of improving their avoidance and treatment.

Predictability and Practicality of Image-Based Scoring Systems for Patient Assessment and Outcome Stratification During Percutaneous Nephrolithotomy: a Contemporary Update

Preoperative nomograms offer systematic and quantitative methods to assess patient- and stone-related characteristics and their impact on successful treatment and potential risk of complication. Discrepancies in the correlation of perioperative variables to patient outcomes have led to the individual development, validation, and application of four independent scoring systems for the percutaneous nephrolithotomy: Guy's stone score, S.T.O.N.E. nephrolithometry, Clinical Research Office of the Endourology Society nomogram, and Seoul National University Renal Stone Complexity. The optimal nomogram should have high predictive ability, be practically integrated into clinical use, and be widely applicable to urinary stone disease. Herein, we seek to provide a contemporary evaluation of the advantages, disadvantages, and commonalities of each scoring system. While the current data is insufficient to conclude which scoring system is destined to become the gold standard, it is crucial that a nephrolithometric scoring system be incorporated into common practice to improve surgical planning, patient counseling, and outcome assessment.
