Efficacy and safety of phosphodiesterase type 5 inhibitors for the treatment of distal ureteral calculi of 5 to 10 mm in size: A systematic review and network meta-analysis

Comparative study between Tamsulosin, Silodosin and Tadalafil as a medical expulsive therapy for lower ureteral stones

OBJECTIVE

To compare the efficacy of Tamsulosin, Silodosin and Tadalafil as a medical expulsive therapy for treatment of distal ureteral calculi.

PATIENTS AND METHODS

Over a period of 6 months (January 2022 to June 2022) this prospective randomized study was conducted on 170 patients with distal ureteric stone ≤ 10 mm. Patients were randomly divided into three groups. Patients in group A received Tamsulosin 0.4mg, in group B received Silodosin, and in group C receive Tadalafil 5 mg. Therapy was given for a maximum of 4 weeks. The rate and time of stone expulsion, the analgesic use, attacks of colic and hospital visits for pain, and adverse effects of drugs were recorded.

RESULTS

Among 170 patients who were enrolled in study, 20 were lost to follow-up (7, 8, 5 in group A, B, And C respective-ly). There was a significant higher stone passage rate in group C than group A and B (90% vs. 70% and 76% respectively; p-value = 0.043) and shorter expulsion time in group C (8.7 ± 3.3 days) vs. group A (12.5 ± 5.2 days) and group B (11.3 ± 4.2 days) with (p-value = 0.001)(highly statistically significant with p-value < 0.001) and increased amount of analgesics required in group A (225 ± 115.7 mg) and group B (163 ± 77.5 mg) when compared with group C (120 ± 55.3 mg).

CONCLUSION

Tadalafil is more effective than Tamsulosin and Silodosin in treatment of patients with distal ureteric stones ≤ 10 mm as regard stone expulsion rate, expulsion time with decreased number of colicky episodes and side effects.

Efficacy of tamsulosin versus tadalafil as medical expulsive therapy on stone expulsion in patients with distal ureteral stones: A randomized double-blind clinical trial

Purpose:

To compare the effects of tadalafil, tamsulosin, and placebo as a medical expulsive therapy (MET) for distal ureteral calculi.

Materials and Methods:

This prospective randomized double-blind clinical trial was conducted on 132 renal colic patients with distal ureteric stones (≤10mm) over a period of 12 months. Patients were randomly divided into three groups. Patients in group A received tamsulosin 0.4mg, in group B received tadalafil 10mg, and in group C received placebo. Therapy was given for a maximum of 4 weeks. The rate of stone expulsion, duration of stone expulsion, the dose and the duration of nonsteroidal anti-inflammatory drugs (NSAIDs), analgesic use, and adverse effects of drugs were recorded.

Results:

Demographic profiles were comparable between the 3 groups. Although the stone expulsion rate in group A (72.7%) was higher in comparison to group B(63.6%) and group C(56.8%), it was not considered statistically significant (P=0.294). Shorter mean time to stone expulsion was significantly observed in group A (17.75±75), than group B(21.13±1.17) and group C(22.25±1.18) (P=0.47). The mean number of analgesic use was 9.8±5.09 days in group A, 14.6±7.9 days in group B, and 12.6±22.25 days in group C, this difference was significant (P=0.004). The analgesic requirement (doses of NSAIDs and pethidine) in group A was significantly lower than other groups (P<0.05). Also, patients in group A reported fewer headaches compared to other groups (P=0.011).

Conclusion:

Tamsulosin as medical expulsive therapy is more effective for distal ureteric stones with less need for analgesics and less stone expulsion time than tadalafil.
