Efficacy of Intramuscular Ketorolac for Preventing Renal Colic Post Stent Removal: Randomized Controlled Trial.

PURPOSE: The treatment of stones ureteroscopically is associated with postoperative pain, thought to be due largely to the use of ureteral stents. In some, stent removal precipitates renal colic that can last from minutes to hours. We sought to determine if intramuscular ketorolac could reduce post-stent removal renal colic. MATERIALS AND METHODS: We performed a prospective, randomized, double-blind, placebo-controlled trial assessing the effects of ketorolac administered at time of stent removal. Patients were randomized to receive an intramuscular ketorolac 30 mg or placebo immediately prior to stent removal. Patients were contacted 1 and 7 days after stent removal to assess pain, need for opioids, emergency department or clinic visits and the need for surgical/medical interventions. RESULTS: A total of 124 patients (62 patients each in the control and treatment groups) were included in the study. The groups were comparable in demographic/operative characteristics. No difference in mean pain scores or proportion of patients who experienced severe pain at 1 and 7 days post stent removal was detected between groups. However, use of ketorolac resulted in significantly fewer renal colic-related unplanned emergency department/clinic visits in the treatment group (2%) compared with the control group (13%, p=0.032). CONCLUSIONS: Although administration of ketorolac prior to stent removal does not significantly reduce overall subjective pain experienced post stent removal compared to placebo, it does reduce the likelihood of severe renal colic requiring emergency department or office visits. Eligible patients may benefit from routine use of ketorolac injection at the time of stent removal.

Role of Sexual Intercourse after Shockwave Lithotripsy for Distal Ureteral Stones: A Randomized Controlled Trial.

PURPOSE: To explore whether sexual intercourse is beneficial to the clinical outcome of SWL for ureteral calculi of 7-15 mm in the distal ureter. MATERIALS AND METHODS: Between March 2016 and January 2017, 225 patents with a stone (7-15 mm) in distal ureter were randomly divided into three groups after SWL: Group 1 was asked to have sexual intercourse at least three times a week, Group 2 was administered tamsulosin 0.4 mg/d and Group 3 was received standard therapy alone and served as the controls. Stone free rate, time to stone expulsion, pain score at admission, number of hospital visits for pain and steinstrasse were recorded in 2 weeks. RESULTS: 70 patients in Group 1, 71 patients in Group 2 and 68 patients in Group 3 were enrolled to the study. At the end of the first week and the second week, the stone free rates for Group 1 (68.6%, 80.0%) and Group 2 (69.0%, 81.7%) were approximately the same, but were significantly higher than Group 3 (50.0%, 63.2%) (P = .031, P = .022). The VAS scores of Groups 1 and 2 were slightly higher than those of Group 3 (P = .233). The number of patients in Group 3 who visited the emergency room for pain was significantly higher than in the other two groups (P = .015). At the end of the second week, the incidence of steinstrasse in Groups 1 and 2 was significantly lower (2.9%, 2.8% vs 11.8%) (P = .034). CONCLUSION: At least three sexual intercourses per week after SWL can effectively improve the stone free rate, reduce the formation of steinstrasse and relieve renal colic. It provides a choice for urologists in the SWL treatment of lower ureteral calculi.

Enfrentamiento del cólico renal en urgencia / Confrontation of renal colic in urgency

Ureteral colic as a nosologic entity, is part of a select group of pathologies that present themselves in an intense and acute form, in which the patient suffers excruciating pain and demands quick diagnosis and treatment. It’s also a common disease in our emergency service, like in other countries. The aim of the present study is to standardize and deepen the management and treatment of ureteral colic, from the perspective of the emergency medicine...

[Treatment of renal colic with double-J stent during pregnancy: a report of 25 cases].

OBJECTIVE: There is no consensus on the treatment of renal colic, a hazardous condition for both pregnant women and their fetus during pregnancy. The present study was to evaluate the therapeutic safety and efficacy of double-J stent. METHODS: Twenty-five pregnant women were admitted into our hospital for renal colic between January 2008 and June 2009. The mean age was (28.3 ± 4.9) years old. And the mean gestational week was (20.1 ± 6.9) weeks. The diagnostic and therapeutic procedures were as follows: (1) Upon admission, routine urine and blood tests, chemistry panel and ultrasonography were performed. (2) Analgesics or antispasticity drugs were dispended to the patients, such as progesterone. (3) Magnesium sulfate was used for anti-inflammation. (4) If renal colic was not relieved, a double-J stent was inserted into the ureter via cystoscopy. At pre-, intra- and post-operation, an obstetrician monitored the fetal heart and uterine contraction. (5) Ultrasonography was conducted to check the location of double-J stent. (6) After delivery, the women underwent ESWL (extracorporeal shock wave lithotripsy) and then the double-J stent was extracted. RESULTS: Five (20%, 5/25) patients had a positive previous history: three for renal calculus (n = 3), solitary kidney (n = 1) and reimplantation of ureter (n = 1). Only one patient run a high fever of 40°C. Most patients (84%) had a positive percussion over renal regions. Only 6 patients (24%, 6/25) were found to have a great quantity of red blood cells in urine. Half of the patients showed 10 - 20 white blood cells (WBC) per high power field in urine. Fifteen patients (60%, 15/25) had an elevated count of WBC in routine blood test. Only one patient was with elevated serum creatinine because of her solitary kidney. The calcium level decreased in 8 patients (32%, 8/25). All patients suffered hydronephrosis while 18 patients (72%, 18/25) were not found with calculus in ureters or kidneys. Pain of six patients (24%, 6/25) was relieved after the dosing of analgesics. Eighteen patients (72%, 18/25) underwent double-J stent insertion and 1 patient (4%, 1/25) received percutaneous renal puncture. Then pain was relieved and hydronephrosis vanished. After delivery, calculi were treated properly and then the double-J stent were extracted. Iconography showed no residual calculi. CONCLUSION: For pregnant women with renal colic, retrograde intra-ureteral cannula of double-J stent is both safe and effective. It should be recommended for all renal colic women during pregnancy with or without calculus after the ineffective dosing of analgesics.

[Experience in phytotherapy in nephrolithiasis patients after extracorporeal shock-wave lithotripsy].

Our study of efficacy of Prolit-septo phytotherapy following extracorporeal shock-wave lithotripsy (ESWLT) in patients with nephrolithiasis has demonstrated that Prolit-septo noticeably reduces the time of evacuation from the urinary tract of the destructed stone fragments as well as renal colic incidence and renal inflammation exacerbation.
