Study Type – Therapy (RCT) Level of Evidence 1b What's known on the subject? and What does the study add? Results of our study showed that intravenous papaverine hydrochloride plus suppository sodium diclofenac were more effective than diclofenac sodium suppository alone in the treatment of acute renal colic. Therefore, intravenous papaverine hydrochloride may be a beneficial supplemental therapy to relieve renal colic pain, particularly in combination with NSAIDs. OBJECTIVE To assess the efficacy of papaverine hydrochloride combined with a diclofenac sodium suppository to relieve renal colic compared with diclofenac suppository monotherapy, as the effect of phosphodiesterase inhibitors on ureteric muscles might reduce the pain of renal colic. PATIENTS AND METHODS A prospective, double‐blind clinical study was performed. In all, 550 patients aged 17–55 years with acute renal colic were randomised to two groups. Patients in one group (group A) received a diclofenac suppository (100 mg) plus saline 0.9% (placebo) and the other group (group B) received a diclofenac suppository (100 mg) plus intravenous (i.v.) papaverine hydrochloride (1.5 mg/kg up to120 mg). Pain intensity was assessed using a visual analogue scale (VAS) at 0, 20 and 40 min after treatment. Further analgesia was provided at the patients' request (25 mg pethidine intramuscularly). RESULTS Baseline characteristics (sex, age, past history of similar pains) were similar in the two groups. There were significant differences in VAS pain scores between 0 and 20 min and 0 and 40 min in both groups (P < 0.001). At the end of study, 71.1% of patients in group A and 90.9% of patients in group B reported pain relief and did not require pethidine, respectively. Significantly more patients in group A required further analgesia. CONCLUSIONS According to our results, i.v. papaverine hydrochloride plus a diclofenac suppository were more effective than the diclofenac suppository alone for treating acute renal colic. Therefore, i.v. papaverine hydrochloride is a beneficial supplemental therapy to relieve renal colic pain, particularly combined with non‐steroidal anti‐inflammatory drugs.

There were no significant differences in terms of patency and pregnancy rates between MOLVV and TLMVV methods, but the MOLVV technique offers a decreased cost and operative time, and a simplified procedure.

To compare the amount of the kidney displacement in the complete supine percutaneous nephrolithotripsy (PCNL) to the prone PCNL during getting renal access. Thirty-three patients were randomly divided into two groups. The patients in group A were placed in the complete supine position and the patients in group B in the prone position. Amounts of the kidney displacement in three states and other data were analyzed. The mean amount of the kidney displacement in the complete supine PCNL was 10.1 ± 7.9 mm in stage 1, 10.7 ± 8.28 mm in stage 2 and 12.2 ± 10.4 mm in stage 3. The mean amount of the kidney displacement in prone PCNL was 16.6 ± 5.8 mm in stage 1, 16.2 ± 6.3 mm in stage 2 and 17.6 ± 6.7 mm in stage 3. In stages 1 and 2, a significant difference between the two groups derived from the mean amount of the kidney displacement, but the difference was not statistically significant in stage 3. Adjusted for age, gender, BMI, stone burden and position of PCNL, prone position was a predictor caused significantly more displacement in all three stages. Among other predictors, only BMI had a significant effect on the amount of the kidney displacement (in stages 2 and 3). Performing PCNL in the complete supine position is safe and effective and leads to less kidney displacement during getting renal access and therefore, it may be considered in most patients requiring PCNL.
