Meta-analysis of the efficacy of sexual intercourse for distal ureteric stones

Deciding on a novel predictive value to gauge how well patients with lower ureteric stones respond to medical expulsive therapy

This study, conducted over 4 years in Baghdad, Iraq, aimed to determine the importance of ureteric jet assessment in medical expulsive therapy (MET) for distal ureteral stones. A total of 156 patients with distal ureteral stones (≤ 10 mm) participated, and their ureteric jets were observed using a color Doppler scanner before and after 2 weeks of MET. The main focus was the success rate of stone expulsion. Our results showed that 50% of patients had detectable ureteric jets after 2 weeks of MET, and 21.8% experienced successful stone expulsion. After 4 weeks, 23.7% achieved stone expulsion, while 54.5% still had remaining stones. Patients who had a positive baseline ureteric jet were significantly more likely to successfully expel their stones. This study highlights the importance of monitoring ureteric jet movement in MET for distal ureteral stones.

Efficacy of sexual intercosurse in the spontaneous passage of distal or intramural ureteral stones: a randomsized controlled trial

Background

The role of sexual intercourse as an alternative treatment approach for ureteral stones (UTSs) is a recent area of investigation with only small sample-sized studies. This study aims to evaluate the role of sexual intercourse in the spontaneous passage of distal or intramural UTSs via a larger sample size.

Materials and methods

The study population included cases that had either a distal ureteric or an intramural radiopaque stone. The patients were divided into two groups; group A was instructed to engage in sexual intercourse two to three times per week while also receiving symptomatic treatment for 4 weeks. Group B received symptomatic treatment alone and was instructed to abstain from sexual intercourse or masturbation for the same period.

Results

A total of 160 male patients were enrolled in this study. The ages of the patients ranged from 21 to 58 years. The rate of stone expulsion after 2 weeks was 68.18% in group A and 53% in group B (P=0.053). The expulsion rate after 4 weeks was 80% in group A and 68.4% in group B (P=0.072). The mean expulsion time was 13.9±5.4 days for the experimental group and 15.2±6.7 days for the control group (P=0.179). The experimental group required fewer analgesic injections in comparison to the control group (P<0.05).

Conclusion

While the role of sexual intercourse in facilitating the passage of distal or intramural UTSs cannot be fully established, it may aid to some extent. However, it should not be relied upon as a standalone treatment modality.

2022 Recommendations of the AFU Lithiasis Committee: Management of symptomatic urinary stones

The acute situation, caused by an obstructive stone, is defined by a renal colic that may be uncomplicated, complicated, or at risk in specific conditions. Its management may be medical or require interventional treatment by extracorporeal shockwave lithotripsy, endoscopic removal, or ureteroscopy. METHODOLOGY: These recommendations were developed using two methods, the Clinical Practice Recommendations (CPR) and the ADAPTE method, in function of whether the question was considered in the European Association of Urology (EAU) recommendations (https://uroweb.org/guidelines/urolithiasis) [EAU Guidelines on urolithiasis. 2022] and whether they could be adapted to the French context.

[Renal colic: How to calm and optimize the stone expulsion? Which treatment for pregnant women and children?]

INTRODUCTION

The aims of this narrative review was to report on the contemporary data of renal colic (RC) in terms of epidemiology and pressure on emergency structures and also to describe the latest therapeutic developments about uncomplicated RC, depending on the pediatric, adult and pregnancy population.

MATERIAL AND METHODS

A request to the health surveillance network for emergencies and deaths (SurSaUD®, Santé Publique France) revealed original data on the contemporary epidemiology of renal colic. A narrative synthesis of the articles (French, English) available on the Pubmed database was produced in June 2021.

RESULTS

Renal colic represents 1.1% of the annual total of emergency room visits. The mean age at admission was 45 years and 62% of patients were men. NSAIDs and Paracetamol are the most effective analgesic treatments and should be given priority over opioids. Non-drug analgesic treatments by tactile stimulation probably have a place in the CN management, particularly in case of contraindications. Among the validated treatments, alphablockers allow better expulsion when the stone is located in the pelvic ureter and if its size is between 5 and 10mm in diameter. In pregnant women, the predominant problem is to confirm the diagnostic. If there is a strong suspicion, MRI or a low-dose CT scan is possible. Ureteroscopy is feasible in particular in the first part of pregnancy to avoid iterative ureteral catheter changes. The care for children is now based on that of adults.

CONCLUSION

The renal colic care pathway in 2021 can benefit from various optimizations in the field of expulsion and analgesic treatments. Good knowledge of the specific situations in pregnant women and children allowing to improve the quality of care.

Comparison of the Efficacy of Male Sexual Activity Versus Alpha-Blockers in the Expulsion of Distal Ureteric Stones: A Systematic Review and Meta-Analysis

Globally, the prevalence of urolithiasis is increasing, with limited effective treatment options. Though debate exists within the literature, the use of medical expulsive therapy (MET) for distal ureteric stones in the form of alpha-blockers is commonplace. Alpha-blockers work via the inhibition of norepinephrine, resulting in a small degree of distal ureteric relaxation. Nitric oxide (NO), the main neurotransmitter involved in penile erection, causes smooth muscle relaxation of the distal ureter. It is hypothesised that these alternative pathways may achieve the same desire clinical effect. To our knowledge, this is the first meta-analysis comparing the efficacy of male sexual activity, in the form of intercourse or masturbation, to alpha-blockers in the expulsion of ureteric stones. We conducted a comprehensive search of electronic databases (PubMed, MEDLINE, EMBASE, SCOPUS, CENTRAL and Google Scholar), identifying studies comparing male sexual activity versus alpha-blockers, in male patients with distal ureteric stones. The Cochrane risk-of-bias tool was used to assess the included studies. For data analysis, a random effects model was used in the event of significant heterogeneity (>75%), with fixed-effects modelling in the event of low-moderate heterogeneity. A search of electronic databases found three randomised control trials (RCTs), enrolling a total of 262 patients. There was no statistically significant difference observed when patients engaged in sexual activity rather than alpha-blocker, when looking at stone expulsion rate at two weeks (P=0.36), expulsion rate at four weeks (P=0.57), or the mean stone expulsion time (P=0.21). Furthermore, there was no significant difference observed when looking at analgesic requirements (P=0.43), or the requirement for additional procedures (P=0.57). Our meta-analysis demonstrated that male sexual activity as an alternative therapy for distal ureteric stones had comparable outcomes to the use of alpha-blocker, proving a viable alternative therapy in those patients wishing to avoid pharmacological management.

Evaluation of the efficacy of masturbation on distal ureteral stones: a prospective, randomized, controlled study

PURPOSE

To evaluate the effect of masturbation on the spontaneous expulsion of distal ureteral stones 5-10 mm in size.

MATERIAL AND METHODS

A total of 128 men with distal ureteral stones were randomly divided into 3 groups. All patients received standard medical therapy. Patients in group 1 (n = 43) were instructed to masturbate at least 3-4 times a week, patients in group 2 (n = 41) received tamsulosin 0.4 mg/day, and patients in group 3 (controls, n = 44) received standard medical therapy alone. Rates of expulsion, need for analgesic, and ureterorenoscopic lithotripsy were compared between the groups.

RESULTS

The mean ages of the patients in groups 1, 2, and 3 were 37 ± 5.0, 37.6 ± 4.6, and 38.4 ± 6.8 years, respectively (p = 0.7). The mean stone size in each group was 6.93 ± 1.1 mm, 7.1 ± 0.9 mm, and 6.87 ± 1.1 mm, respectively (p = 0.4). Spontaneous passage rates in groups 1, 2, and 3 were 81.4%, 80.5%, and 43.2%, respectively, and were significantly higher in group 1 (p = 0.001) and group 2 (p = 0.001) when compared with group 3. Analgesic requirement in groups 1, 2, and 3 was 1.7 ± 0.6, 1.5 ± 0.6, and 1.8 ± 0.6 times per day, respectively, and was significantly lower in the tamsulosin group than in the control group (p = 0.004) CONCLUSION: Masturbation and tamsulosin increased the spontaneous passage of distal ureteral stones 5-10 mm in size. Masturbating at least 3-4 times a week was as effective as tamsulosin. Masturbation and tamsulosin also reduced the need for ureterorenoscopic lithotripsy.
