[Extracorporeal lithotripsy in the treatment of renal colic].

Renal colic arises in acute ureteral obstruction and indicates a sharp rise in intrapelvic pressure (up to 150 mm Hg). The diagnosis of renal colic is made basing on direct and indirect measurements of intrapelvic pressure. Ultrasound in renal colic detects dilatation of the calices and pelvis on the colic side, ureterolith can be also revealed by ultrasound. The authors used extracorporeal lithotripsy for fragmentation of the stone and colic relief in 68 patients. The colic stopped in all the cases. This method is extremely valuable in cases when spasmolytic and analgetic drugs, other conservative modalities fail.

[Imaging studies of excretory urography and computed tomography scan for patients suffering from renal colic].

Renal colic mainly due to urolithiasis is one of the most common morbid conditions in urology and commonly seen in the urology emergency clinic. Imaging studies were performed to evaluate the upper urinary tract of 29 patients suffering from renal colic in the 2 years between November, 1994 and October, 1996. After intramuscular injection of the analgesic (pentazocine, 15 mg), all 29 patients were examined by excretory urography (IVP) at the time of the first visit. In some patients abdominal plain computed tomography (CT) scan was performed consecutively even when extravasation of the contrast medium was not seen. Spontaneous peripelvic extravasation was seen in 14 patients (11 males and 3 females) with urolithiasis; 7 of them were diagnosed by IVP, 5 by IVP plus CT scan and 2 with CT scan only. IVP imaging study followed by plain abdominal CT scan is useful even when the contrast medium is not extravasated on IVP in patients suffering from renal colic.

Wireless teleradiology for renal colic and renal trauma.

BACKGROUND PURPOSE: Image transmission is an integral part of telemedicine, allowing evaluation of patients at remote sites. We developed a simple method of wireless transmission of digital images to a hand-held computer (PDA) and evaluated its feasibility and diagnostic accuracy in patients with acute renal colic or renal trauma. MATERIALS AND METHODS: The CT images from 11 patients with suspected renal colic and one patient with renal trauma were transmitted using a cellular telephone with a wireless modem link to a PDA (Sony Clie 615C). A diagnostic interpretation was recorded for the presence/absence of an upper-tract stone, stone location, estimated stone size, and signs of upper-tract obstruction. Radiologic staging of trauma was provided in the patient with a renal injury. Comparison was made with the final dictated report of a staff radiologist. RESULTS: Ten CT sets of patients with renal colic were used for comparison, the remaining one being excluded because of ambiguity in the final radiology report. An average of 5.9+/-1.6 images, average size 32.2+/-5.2 kb (range 21-42 kb) for each patient were sent at an average speed of 1 kb/sec. Interpretation correctly identified stone presence in 80%, hydronephrosis in 100%, and perinephric stranding in 80% and stone size within 1+/-1 mm. A stage-3 renal trauma was correctly identified and staged. CONCLUSION: Wireless teleradiology to PDA units provides image quality sufficient for diagnostic interpretation. Anticipated improvements in wireless transmission and PDA screen image resolution will enhance the speed, quality, and quantity of images transmitted. Wireless teleradiology may facilitate convenient rapid evaluation of patients at remote sites.

Non-contrast spiral CT for patients with suspected renal colic.

Renal colic, defined as acute flank pain caused by the passage of a ureteral calculus, is a common condition, but the correct diagnosis may not be apparent clinically. For decades, intravenous urography has been the test of choice for evaluating patients with suspected renal colic. Recently, unenhanced (non-contrast) helical CT has been shown to be an accurate and highly effective examination which can be used instead of intravenous urography. In this article, the technique is reviewed in detail, including its advantages and potential pitfalls.

Renal autotransplantation for recurrent renal colic.

Renal autotransplantation as an alternative to ileal interposition has been done successfully in patients with repetitive episodes of renal colic. Urinary tract continuity has been re-established by anastomosis of a Boari tube directly to the renal pelvis. This has resulted in easy egress of recurrent calculi without pain. Furthermore, the musculature of the Boari tube seems to be adequate for prevention of vesicorenal reflux. The procedure has been devoid of electrolyte and mucous urinary retention problems associated with ileal interpositionand it is advocated as an alternative in the management of such patients when medical therapy fails.

[Renal colic and renal calculus].

A positive diagnosis of urinary stone was made in 183 of 407 patients (44.9%) with renal colic seen in the emergency room. 182 (44.7%) had normal intravenous pyelograms, 26 (6.4%) had evidence of dilatation of the urinary system, possibly due to the passage of a stone, and 16 (3.9%) had other pathological urinary conditions, such as double collecting system or cysts. Stones were located in the upper urinary tract in 28.4%, in the midureter in 21.9%, and in the lower ureter in 49.7%. There was a statistically significant correlation between recurrent episodes of left-sided renal colic, erythrocytes in the urine and the presence of a stone in the urinary tract. No ethnic differences were found, nor was there a difference in the rates of stones found in those who were hospitalized and in those who were not.

Toradol, an NSAID used for renal colic, decreases renal perfusion and ureteral pressure in a canine model of unilateral ureteral obstruction.

Toradol is a new parenteral, nonsteroidal anti-inflammatory drug which is efficacious in treating renal coli. In the present experiments, Toradol was administered to both control dogs and dogs with unilateral ureteral obstruction. In control dogs, Toradol had no effect on RBF or GFR, despite inhibition of renal prostaglandin synthesis (measured as urinary prostaglandin release). In contrast, RBF fell acutely by 35% (p < 0.001) within 15 minutes of Toradol administration in the setting of ureteral obstruction; contralateral RBF was unaffected. Ipsilateral ureteral pressure also fell. Changes in RBF and ureteral pressure, together with the known effects of NSAIDs on pain pathways, may contribute to the pain relief observed clinically with Toradol. However, the abrupt changes in renal hemodynamics brought on by Toradol to the obstructed kidney may compromise renal reserve, and Toradol should be used cautiously in treating renal colic.

[Efficient, immediate or emergency ESWL: an attractive strategic alternative to be considered in the treatment of renal colic!].

INTRODUCTION: Renal colic due to acute ureteral obstruction caused by lithiasic impact results in severe rise of intracavitary pressure. Traditional drug therapy (painkillers, anti-inflammatories, spasmolytics) is symptomatic and provisional, and pain can reappear when obstruction is maintained. A pathoetiological approach would be the ultimate therapy vs the symptomatic one. MATERIAL AND METHODS: From the beginning, the approach used at the Lithiasis-Lithotrity Unit at the FJD, once the ureteral stone is accurately identified during a renal colic, is that of immediate or emergency "in situ" SWEL together with the usual drug therapy. 15% of 2100 cases of ureteral lithiasis treated (1991-1999) were renal colic. RESULTS: Renal colic can be resolved in all cases (100%) even when fragmentation may be partial and/or require a second deferred SWEL on remnants of the first lithiasis. When obstruction has been resolved, pain does not reappear as it happens with the effects of analgesics. DISCUSSION: Placement of a ureteral catheter or nephrostomy for analgesia in order to perform deferred SWEL of the ureteral stone origin of the acute ureteral obstruction and the renal colic, do not improve SWEL results. There are physical reasons to support the practice of immediate or emergency "in situ" SWEL during a renal colic. Fragmentation of the obstructive stone together with the resulting ureteral oedema allow urine passage. Intracavitary pressure and pain disappear when the obstruction is withdrawn. CONCLUSIONS: Immediate, "in situ" or emergency SWEL in cases of obstructive ureteral stones during a renal colic, is an attractive strategic alternative for drug therapy that should be considered mainly in institutions with means to perform the procedure.

Nonsteroidal anti-inflammatory drugs (NSAIDs) versus opioids for acute renal colic.

BACKGROUND: Renal colic is a common cause of acute severe pain. Both opioids and nonsteroidal anti-inflammatory drugs (NSAIDs) are recommended for treatment, but the relative efficacy of these drugs is uncertain. OBJECTIVES: To examine the benefits and disadvantages of NSAIDs and opioids for the management of pain in acute renal colic. SEARCH STRATEGY: We searched the Cochrane Renal Group's specialised register (May 2003), the Cochrane Central Register of Randomised Controlled Trials (CENTRAL - The Cochrane Library issue 2, 2003), MEDLINE (1966 - 31 January 2003), EMBASE (1980 - 31 January 2003) and handsearched reference lists of retrieved articles. SELECTION CRITERIA: Randomised controlled trials (RCTs) comparing any opioid with any NSAID, regardless of dose or route of administration were included. DATA COLLECTION AND ANALYSIS: Data was extracted and quality assessed independently by two reviewers, with differences resolved by discussion. Dichotomous outcomes are reported as relative risk (RR) and measurements on continuous scales are reported as weighted mean differences (WMD) with 95% confidence intervals. Subgroup analysis by study quality, drug type and drug route have been performed where possible to explore reasons for heterogeneity. MAIN RESULTS: Twenty trials from nine countries with a total of 1613 participants were identified. Both NSAIDs and opioids lead to clinically significant falls in patient-reported pain scores. Due to unexplained heterogeneity these results could not be pooled although 10/13 studies reported lower pain scores in patients receiving NSAIDs. Patients treated with NSAIDs were significantly less likely to require rescue medication (RR 0.75, 95% CI 0.61 to 0.93, P = 0.007), though most of these trials used pethidine. The majority of trials showed a higher incidence of adverse events in patients treated with opioids, but there was significant heterogeneity between studies so the results could not be pooled. There was significantly less vomiting in patients treated with NSAIDs (RR 0.35, 95% CI 0.23 to 0.53, P < 0.00001). In particular, patients receiving pethidine had a much higher rate of vomiting compared with patients receiving NSAIDs. Gastrointestinal bleeding and renal impairment were not reported. REVIEWER'S CONCLUSIONS: Both NSAIDs and opioids can provide effective analgesia in acute renal colic. Opioids are associated with a higher incidence of adverse events, particularly vomiting. Given the high rate of vomiting associated with the use of opioids, particularly pethidine, and the greater likelihood of requiring further analgesia, we recommend that if an opioid is to be used it should not be pethidine.

The role of the radionuclide renal study in the management of renal colic.

If renal colic is suspected in the patient presenting with acute flank or lower abdominal pain it must be established whether or not the affected kidney is obstructed and whether there is functional impairment that may require urological intervention. The radionuclide renal study developed in this hospital and used routinely for over 10 years can reveal obstruction when the results of commonly used tests are negative. It also provides information on renal function, morphology and blood flow. It is a cost-effective, safe and reliable procedure for the initial investigation of patients presenting with suspected renal colic.

Single dose dipyrone for acute renal colic pain.

BACKGROUND: Renal colic pain is extremely painful and requires immediate treatment with strong analgesics. Dipyrone is the most popular non-opioid first line analgesic in many countries but in others it has been banned (e.g. USA, UK) because of its association with blood dyscrasias such as agranulocytosis. Since dipyrone is used in many countries (e.g. Brazil, Spain) there is a need to determine the benefits and harms of its use to treat renal colic pain. OBJECTIVES: To assess quantitatively the analgesic efficacy and adverse effects of single-dose dipyrone in adults with moderate to severe renal colic pain. SEARCH STRATEGY: Published reports were identified from electronic databases (MEDLINE, EMBASE, the Cochrane Library, LILACS) and additional studies were identified from the reference lists of retrieved reports. Date of the most recent search: January 2000. SELECTION CRITERIA: Inclusion criteria were: full journal publication; RCT with a double-blind design; adult patients with baseline renal colic pain of moderate or severe intensity; treatment arms which included dipyrone (oral, intramuscular or intravenous administration) and a control; single dose data. DATA COLLECTION AND ANALYSIS: Summed pain intensity and pain relief data were extracted and converted into dichotomous information to yield the number of patients with at least 50% pain relief over 15-30 minutes, 1-2 hours and six hours. The proportion of patients with at least 50% pain relief was calculated. Single dose adverse effect data were collected. MAIN RESULTS: Eleven studies with 1053 patients (550 on dipyrone) met the inclusion criteria. Unfortunately, few data were available for analysis; most analyses were based on the results of single, small trials and statistical pooling of the results was inappropriate. Efficacy estimates were calculated as the weighted mean percent of patients achieving at least 50% pain relief with the range of values from trials contributing to the analysis. However, these estimates were not robust. Commonly reported adverse effects with intravenous dipyrone were dry mouth and somnolence, and one study reported pain at the injection site. Insufficient information was available for safety analyses to be conducted. REVIEWER'S CONCLUSIONS: Limited available data indicated that single dose dipyrone was of similar efficacy to other analgesics used in renal colic pain, although intramuscular dipyrone was less effective than diclofenac 75 mg. Combining dipyrone with antispasmolytic agents did not appear to improve its efficacy. Intravenous dipyrone was more effective than intramuscular dipyrone. Dry mouth and somnolence were commonly reported with intravenous dipyrone. None of the studies reported agranulocytosis.

Intravenous urography revisited in the age of ultrasound and computerized tomography: diagnostic yield in cases of renal colic, suspected pelvic and abdominal malignancies, suspected renal mass, and acute pyelonephritis.

The aim of our study was to assess the diagnostic yield of intravenous urography (IVU) compared to ultrasound (US) and computerized tomography (CT) in cases of renal colic, suspected pelvic and abdominal malignancies, suspected renal mass, and acute pyelonephritis. We retrospectively analyzed the case charts of 216 consecutive patients. The patients had been referred to the Department of Radiology by different hospital departments and local general practitioners. All had undergone clinical examination, US and IVU, in that order. When deemed necessary, conventional tomography was performed. Patients with renal masses also underwent CT. In cases without renal colic and normal US examination, the subsequent IVU failed to detect any further important pathology. Hydronephrosis was equally well detected using US and IVU, however, the level of obstruction was better determined using delayed X-ray films. In 24% of cases of renal colics the initial US was normal, however, the IVU revealed ureteric obstruction. Repeat US 8-12 h later always showed hydronephrosis. In 6 of 34 solid renal masses, IVU and conventional tomography failed to make the correct diagnosis, but never could the patient be spared a subsequent CT. IVU is only indicated if US shows hydronephrosis. In cases of renal colic, repeat US is necessary to diagnose the possibly developing hydronephrosis. Clinical history, US and a plain abdominal image will suffice to make the diagnosis. Renal masses always require CT. In these cases, IVU is not necessary. There is no indication left for conventional renal tomographies.

Renal colic in pregnancy.

Renal calculi are an infrequent but significant management problem during pregnancy. We reviewed all cases of renal colic occurring during pregnancy between 1979 and 1990 at Grace Hospital, a tertiary care obstetrical hospital in Vancouver, British Columbia. Of the patients 80 had a discharge diagnosis of renal colic and pregnancy during this 11-year period. Calculi were confirmed in 57 patients. Of the patients 66% were multiparous and 99% of the calculi occurred during either the second or third trimester. The most common symptom was flank pain seen in 89% of the patients, while greater than 95% displayed either microscopic or gross hematuria. Methods of radiographic diagnosis included ultrasonography and limited stage excretory urography. A total of 84% of patients passed stones spontaneously. Indications for urological or obstetrical intervention included persistent pain, sepsis, progressive hydronephrosis, solitary kidney or high grade obstruction. There were 37 procedures done in 23 patients. The most common procedure was placement of a ureteral stent. The complication rate associated with intrapartum intervention and stent passage in the 23 patients was 16%. All patients with a ureteral stent subsequently had spontaneous vaginal delivery without complication. A scheme for managing renal calculi in pregnancy is presented.

Transcutaneous electrical nerve stimulation: an effective treatment for pain caused by renal colic in emergency care.

PURPOSE: Acute renal colic is one of the most anguishing forms of pain in humans. We hypothesized that TENS is an effective pain treatment in patients with acute renal colic. MATERIALS AND METHODS: A total of 100 patients with acute flank pain and suspected renal colic consented to participate in our study. Paramedic 1 recorded baseline parameters at the emergency site and at the end of transportation. Paramedic 2 performed TENS in patients randomly assigned to G1 with actual TENS or to G2 with sham TENS. Pain and anxiety were measured using paper based visual analog scales on a scale of 0 to 100 mm. RESULTS: Of 100 screened patients 73 had renal colic, including 39 in G1 and 34 in G2. There was no significant difference with regard to potentially influencing factors, such as patient age, sex, weight, height, blood pressure and heart rate, pain, nausea and anxiety between the groups before treatment. G1 showed a significant mean pain decrease +/- SD of more than 50% (85.7 +/- 10.5 to 33.3 +/- 16.0 mm, p <0.01). G2 showed no variation in mean pain scores (85.8 +/- 18.0 to 82.6 +/- 14.3 mm). G1 showed changes in the mean anxiety score (69.0 +/- 8.4 to 37.7 +/- 15.1 mm, p <0.01), nausea score (90.7 +/- 9.2 to 44.9 +/- 22.0 mm) and heart rate (92 +/- 10 to 64 +/- 8 bpm), while G2 showed nonsignificant changes. CONCLUSIONS: This trial shows that local TENS is a rapid and effective treatment for renal colic pain. We found TENS to be a good nondrug therapy under the difficult circumstances of out of hospital rescue.
