This article reviews the literature regarding gastrointestinal disturbances in particular in runners. The lower intestinal problems of motility and blood loss are discussed. These problems are directly related to running. These symptoms, especially diarrhea are common and can impact adversely both performance and the health of the athlete. Most cases are relatively benign. The sport medicine clinician should be familiar with the management of these problems in order to optimize the treatment and facilitate return to sport.

The persistent and unexplained crying of newborns, attributed to colic, is a frequent problem in paediatrics. Usually considered harmless, it can however have consequences on the baby's behaviour and emotional regulation. Moreover, mothers often misinterpret the crying. Faced with the maternal anxiety which is often associated, treatment must be multifocal.

The care in the emergencies of the renal colic at the adult was the object in 1999 of a conference of consensus of the French Society of Emergency (SFMU) in association with the French Association of Urology and the Society of Nephrology. This already former text was the object of an update in 2008 by the subcommittee of scientific monitoring of the SFMU and was presented to the congress 2008. This public presentation in the presence of an expert urologist allowed to confront this new text with the practices and to publish an updating of the conference of consensus of 1999. A survey of practice was led with the emergency physicians, whose results are presented.

A 97-year old woman presented with a 2-months history of asthenia, loss of appetite, nauseas and intermittent diarrhea. She presented an important colic distension associated to an inflammatory syndrome. Microbiological documentation (blood, urine, saddles stool) was negative. Abdominal computed tomography (CT) showed a 15 cm of diameter (giant) right cortical renal cyst with colic obstruction by external colic compression. A percutaneous cyst drainage was performed allowing the evacuation of 1,500 cc. The fluid culture was positive for Raoultella ornithinolytica and Enterococcus faecalis. No antibiotics were given but inflammatory syndrome remained within normal value. Colic function remained normal.

Introduction: Urinary stones are relatively frequent in pregnant women and raise specific diagnostic and therapeutic problems. The authors conducted a retrospective review of the management of this disease in their establishment., Patients and Methods: Between January 1999 and December 2003, out of a total of 10,398 parturients, 48 pregnant women were hospitalised for renal colic, that is, incidence of 0.04%. The medical records of these patients were retrospectively reviewed and clinical, laboratory, treatment and outcome data were analysed., Results: Standard analgesic treatment, comprising paracetamol and an antispasmodic, achieved pain relief in 84% of cases. A concomitant short course of corticosteroid therapy in cases of renal colic refractory to standard treatment was effective in 71% of patients and allowed deferral of surgical management in five out of seven cases. A double J stent was placed in all patients requiring urinary diversion, followed by closer ultrasound and bacteriological monitoring throughout pregnancy. Only two patients required surgical management of their stone after delivery. The only obstetric event related to renal colic was induction of labour at term in two cases because of foetal distress., Conclusion: The authors propose a two-stage management plan for renal colic in pregnant women resulting in a low maternal and foetal complication rate.

Authors report a case of a 31 years old patient who eliminate a urinary stone which contains a platinium coil. Five years ago, this patient had a percutaneous nephrolithotomy. A persistent hematuria was successfully managed with angioembolization of a lower polar artery branch. One of the coils was deployed too distally. It was not efficient, it rolled itself up in the pseudoaneurysm cavity. Different physio pathological hypothesis are developed to explain this expulsion.

In 2006, 70 to 80% of calculi are treated with extracorporeal lithotripsy, 7% with percutaneous nephrolithotomy, 5 to 15% with ureteroscopy and less than 1% with laparoscopic surgery or open procedure. Twenty years after its introduction, extracorporeal lithotripsy is still predominantly used. Today though, its indications are better defined. At the same time, considerable advances have been made in the field of intracorporeal lithotripsy, which have contributed to the development-of ureteroscopy and percutaneous nephrolithotomy. Nowadays, urologists have to master all surgical techniques to best adapt their therapeutic decisions. Finally, they should always keep in mind that treatment for urolithiasis is not limited to surgery. A medical management is essential to prevent recurrences; it concerns all patients with lithiasis, from the very first event, and it is based on a systematic screening for risk factors. This first-intention etiological study is carried out in an ambulatory setting, it is easy and cost-effective. It essentially consists in a morphological and constitutional analysis of the calculus by infrared spectrophotometry. Once risk factors for nephrolithiasis have been identified, measures to readjust patient diet and a medical treatment, when necessary, can be implemented.

Introduction: This study was designed to evaluate the efficacy of ESWL in the management of acute renal colic., Material and Method: From January 2003 to August 2003, 102 patients were hospitalised for renal colic. We treated 57 patients by ESWL using an EDAP LT 02 apparatus. Successful treatment was defined by stone fragmentation on the plain abdominal x-ray at 24 hours associated with resolution of pain after only one ESWL session., Results: The overall complete success rate after only one ESWL session was 49%. Results according to site: UPJ stones: 46% of success, lumbar ureter: 14%, iliac ureter: 33%, pelvic ureter: 66%. According to size: < 5 mm: 57% of success, 6 to 10 mm: 70%, 11 to 15 mm: 27%, > 15 mm: 0%. No difference in success rate was observed according to the cumulative energy delivered or according to the duration of ESWL sessions., Conclusion: ESWL can be considered to be a first-line treatment for acute renal colic. Its best indications correspond to pelvic or UPJ stones less than 10 mm in diameter. We believe that it is useless to exceed a duration of 30 min per ESWL session at a frequency of to 2 Hz.

Urinary obstruction has three different clinical aspects: acute, chronic and intermittent. Imaging modalities and diagnostic strategies are different for each of them. Although the morphologic analysis is accurate for all imaging modalities, the diagnosis of hydronephrosis may not be so easy, except for major typical form. There are some pitfalls, for instance the presence of parapelvic cysts at ultrasound and difficulties for initial or minor forms. Nowadays, IVU is still in routine the best examination to assess renal function. In the near future, MRI should be able to give useful information for both morphologic and functional status and take an important role in the evaluation of urinary obstruction.

A hydrolysate of proteins is considered to be adapted to treatment of allergy to cow's milk proteins when it is tolerated by 90% of allergic children. This suggestion implies that 10% of the children who are allergic to cow's milk proteins do not tolerate the preparations based on hydrolysates of proteins and presupposes the case of intolerance or allergy henceforth widely reported. The diagnosis must mention before the existence or the persistence in an infant fed with a hydrolysate of proteins of non-specific clinical signs often attached to more frequent pathologies, such as gastro-oesophageal reflux or colic. Substitution of a hydrolysate by another is one alternative, but the level of residual peptides of protein hydrolysates explains only the cases of severe allergy, the child may show reactions to these residual epitopes. The alternative is use of a formulation based on amino-acids, which allows diagnosis by an elimination-provocation test of protein hydrolysate. An elementary formulation based on amino-acids may permit to await the period of acquisition of tolerance.

For many years soy bean-based formulas (SBBF) were the only dietary product used for infants with cow's milk intolerance. At the present time, their place in infant nutrition is reduced as a result of the availability of new dietary products without lactose and/or cow's milk proteins and the recognition of soy bean protein allergy. There is no evidence that SBBF have any efficiency in infant colic. SBBF have no indication in the prevention of allergy, nor in premature infants' nutrition. Their main indication is the feeding of infants of vegetarian parents who do not want to use cow's milk products. Studies have shown that SBBF contain large quantities of phytoestrogens, particularly isoflavone. Because of experimental data suggesting a possible deleterious effect of phytoestrogens on the neuroendocrine maturation, the reduction of their content in SBBF must be considered.

Ureterolithiasis is a common disease responsible for a large number of admissions in emergency departments and a wide utilization of imaging studies. The purpose of this review was to analyze the respective role of the different available imaging techniques. Intravenous urography is the gold-standard for diagnosis of acute obstruction, but positive detection of a stone may prove difficult at times. US is less accurate than urography for both diagnoses of obstruction and lithiasis, but it represents a non invasive alternative to IVU (no ionizing radiation and no IV contrast). The information obtained from measurements of intra-renal resistive index is poorly contributive. Non contrast helical CT has become the gold-standard for the diagnosis of ureterolithiasis, the two main factors limiting its widespread use are its accessibility and the radiation exposure. Nevertheless, its excellent diagnostic performance tends to dramatically reduce the need for IVU.

Background: Diagnosis of familial benign hypercalcemia can be challenged by the association with a urinary lithiasis, which, in the presence of hypercalcemia, will most frequently lead to affirm primary hyperparathyroidism., Case Reports: We report the case of a 23 year-old patient who presented with a left ureteral stone composed of calcium oxalate. His serum total calcium value was 2.92 mmol/l. Serum PTH value was inappropriately in the normal range (32 ng/l, normal values 10 to 58 ng/l). Hypercalcemia persisted despite a subtotal parathyroidectomy and new investigation biochemical revealed familial benign hypercalcemia., Conclusion: This diagnosis is usually made fortuitously, since most patients have few, if any, symptoms. A past familial history of hypercalcemia and several biochemical features (such as a reduced fractional excretion of calcium, mild hypermagnesemia, and a normal serum inorganic phosphorus level) are helpful dues to the diagnosis of familial benign hypercalcemia. In some cases, however, searching for an inactivating mutation of the extracellular calcium-sensing receptor gene is necessary to distinguish this autosomal dominant disease from primary hyperparathyroidism.

A case has been reported of the spontaneous rupture of the kidney during an attack of nephritic colic. This rare complication is due to excessive pressure in the renal cavities caused by an obstructive ureteral calculus. Complete resolution of the urinoma was obtained after endoscopic fragmentation of the calculus and double J stenting.

Aim of the Study: To describe the population of children allergic to cow's milk protein and their usual substitutes made of protein hydrolysates, and who are efficiently taken care of by using Neocate, an amino acid based formula., Patients and Methods: Allergy to protein hydrolysates was diagnosed in 30 infants, aged from 15 d to 13 months (median = 3 months), who remained symptomatic while receiving a protein hydrolysate for 15 d to 12 months (median = 1.8 months). After a complete clinical and biological evaluation, an amino acid based diet using Neocate was attempted, followed after one month by an oral challenge test with the protein hydrolysate., Results: Symptoms occurred mainly in the digestive tract (25 cases) in the form of regurgitations (18 cases), diarrhea (17 cases) and colicky pain (10 cases); failure to thrive was seen in ten cases. Neocate improved the clinical condition rapidly (within 3-10 d), and allowed the children to gain weight (27.5 +/- 10.8 g/d). Skin prick tests with cow's milk hydrolysates were positive in 13 out of 26 children; total IgE was raised in cases of cutaneous symptoms (six cases), and associated with increased specific IgE for cow's milk. During the intestinal permeability test, the lactitol/mannitol ratio which initially increased, decreased following Neocate (6.58 +/- 2.92% vs. 3.47 +/- 1.58%, P = 0.0004). Multiple food allergies were present in 22 cases. During challenge with a hydrolysate, the clinical reaction was immediate in 13 cases, partially delayed in 13 cases and delayed in four cases., Conclusion: Allergy to cow's milk hydrolysates may occur and has to be considered in the presence of anaphylaxis and also chronic digestive symptoms such as regurgitations, diarrhea and colicky pain, when these symptoms persist during cow's milk free diet.

The authors report the clinical case of a young woman with thrombophlebitis of the right ovarian vein following delivery by caesarean section, initially presenting in the form of renal colic. In the light of a review of the literature, they recall the pathophysiological mechanisms of ovarian thrombophlebitis and the various features observed on imaging examinations. The most frequent clinical features are also described. The authors emphasize the potential, but rare severity of this disease, characterized by the risk of pulmonary embolism, and its treatment, which is usually medical.

Objectives: This prospective study was designed to determine the reliability of noncontrast spiral CT scan, compared to that of intravenous urography (IVU), in the diagnostic assessment of acute renal colic., Material and Methods: 53 patients, admitted with an empirical diagnosis of renal colic after initial assessment, were included and underwent spiral CT scan without contrast agent injection, immediately followed by IVU. These examinations were performed according to a blind protocol by two different radiologists. We initially looked for the presence of stones and/or urinary tract obstruction. Patients with a stone and/or obstruction (urinary tract dilatation) visible on CT scan were then examined for the presence of CT signs associated with stone disease (infiltration of the perirenal and periureteric fat, oedema of the ureteric wall and loss of sinus fat). We calculated the statistical correlation between the presence or absence of obstruction and these accessory signs., Results: 45 stones were recovered (in 36 cases before the two examinations). 36 stones were identified on CT versus only 24 on urography. Urinary tract dilatation was demonstrated in 26 out of 53 cases by both urography and CT. The frequency of accessory signs visible on CT in the presence of stones (n = 36) was 66% for infiltration of periureteric fat, 36% for infiltration of perirenal fat and 75% for oedema of the ureteric wall. In the presence of urinary tract dilatation, these frequencies were 92%, 84% and 60% respectively., Conclusion: Noncontrast spiral CT is a reliable and rapid diagnostic modality for the detection of urinary stones, providing a morphological study equivalent to that of IVU and able to guide appropriate treatment. It should replace IVU in the diagnostic assessment of renal colic.

Choledochal cysts have an increased risk of biliary tract malignancy, induced by reflux of pancreatic juice and anomalous pancreatobiliary ductal junction. We report one case of congenital choledochal cyst in a 68-year-old female whose malignancy was revealed by history of pain and jaundice. Pancreatico-duodenectomy was performed and the patient was alive 6 months later.

Sphincter of Oddi dysfunction (SOD) is an obstructive syndrome of the papilla not resulting from a stone. It may cause recurrent biliary type pain to cholecystectomized patients. SOD is caused by sphincter dyskinesia or benign stenosis. Diagnosis is usually based on symptoms, serum biochemistry, endoscopic retrograde cholangiopancreatography and Sphincter of Oddi manometry. The latter is the best means of evaluating Sphincter of Oddi dynamics. However, because of the many inconveniences of Sphincter of Oddi manometry and of its high morbidity rate, it is seldom used. Non invasive techniques, such as cholescintigraphy, have been developed to replace Sphincter of Oddi manometry in diagnosing SOD. Patients can be cured by sphincterotomy. Certain drugs could also be effective but few controlled studies have been carried out of date.

The objective of this study was to illustrate the diagnostic and therapeutic aspects of renal haematomas based on 3 cases observed in the Casablanca urology department and a review of the literature. In 50% of cases, the haematoma is secondary to adenocarcinoma or angiomyolipoma, requiring specific treatment.

The authors report an unusual case of renal colic occurring in a 44-year-old docker. Intravenous urography showed right ureteral extrinsic compression by an osteophyte of the 3rd lumbar vertebra. After failure of medical treatment, the patient was operated with resection of the osteophyte. The postoperative course was uneventful with reduction of pain.

A case of gallstone ileus in an elderly woman is described and attention is drawn to the insidious clinical presentation and the significance of the often subtle radiological signs. The data from the literature specifies these aspects and allows a more complete review of this relatively rare pathology in order to remind its importance in differential diagnosis to emergency clinicians and radiologists.

Parapyelic cysts are not uncommon. There is usually no clinical expression of these cysts although development within the sinus can cause obstruction leading to acute nephretic colic. We observed two cases of intrasinus parapyelic cysts and another case of obstructive intrapyelic cyst. At ultrasonography, the only sign was hydronephrosis and a junction syndrome could not be eliminated. Intravenous pyelography demonstrated hydronephrosis and in one case a round intrapyelic mass. Computed tomography was required for diagnosis. Surgical exeresis was required due to the pain and compression damage to the parenchyma. This is a rare indication for surgical treatment of simple cysts of the kidney.

The pathophysiology of renal colic is related to tension exerted on the excretory cavities by an obstruction, generally a stone, causing secretion of prostaglandins which, in turn, increase the renal blood flow and glomerular filtration rate. This results in a vicious circle explaining the effect of fluid restriction and NSAIDs.

The objective of this study was to evaluate the performances of the Storz Modulith SL20 lithotriptor. Fifty patients with a total of 52 renal (31) or ureteric (21) stones were treated, in a single session, between June and October 1993. The mean stone diameter was 7.9 mm. All patients were reviewed after 3 months. The complete success rate, with radiological cure, was 65% at 3 months. The partial success rate, defined as fragmentation of the stone with persistence of residual fragments less than 3 mm in diameter, not requiring further treatment, was 12% at 3 months. The failure rate at 3 months was 23%. The commonest complication was renal colic in 12 patients (24%). Two patients developed an extrarenal haematoma. The Modulith SL20 possesses a good detection system: firing is well tolerated under minimal analgesia. Our success rates are slightly lower than those obtained by other teams using the same apparatus.

Cystinuria is an amino acid disease due to a defect of intestinal and renal tubular transport of cystine and various basic amino acids (lysine, arginine and ornithine). The disease is transmitted horizontally according to an autosomal recessive pattern. The overall prevalence is one per 7,000 live births. It is the commonest hereditary disease affecting amino acid transport (MIM 220100). This disease is characterized by excessive urinary excretion of cystine and basic amino acids. From a clinical point of view, almost 50% of homozygotes will develop cystine renal stones with urinary tract infection, renal colic, partial or total obstruction of the urinary tract and possibly loss of renal function.

Lithotripsy has confirmed its place in the treatment of urinary stones and there are now few indications for open surgery in this disease. Lithotripsy used to be rarely used, as it required a great deal of patience on the part of the patient, lying in the water bath, and the medical team. Increasing efficient systems are now available with a marked advantage for patients. Simple analgesia-sedation is often sufficient when requested by the patients and the duration of treatment has been considerably decreased. The authors present a review of their results with the new Lithostar 2 Model C shock wave generator system. The modifications made to this system take into account physical possibilities and medical requirements. As a result of the new configuration of this system, the treatment time per patient has been further decreased, a higher energy is applied to the stones and the disintegration rate is excellent.

A comparative study of the resistivity indices (RI) obtained in both kidneys has been carried out in 30 controls and 60 patients with suspected unilateral acute obstruction of the upper urinary tract. Doppler findings (difference in the mean RI of both kidneys, delta RI) in the pathologic population have been systematically correlated to the data yielded by intravenous pyelography (IVP). In the control population delta RI was always < or = 0.03 (mean delta RI = 0.01, SD = 0.01). Considering that an increase in delta RI > or = 0.05 (> mean RI + 3 SD) is significant, 93% sensitivity and 100% specificity are obtained for the diagnosis of unilateral acute obstruction. Comparison of the resistivity indices of both kidneys is more specific and more sensitive than the assessment of the index on the obstructed side only; it improves the performance of ultrasonography in the initial diagnosis of acute urinary tract obstruction.

This study is a complete review of the common complications related to incomplete ureteral duplication, and based on three clinical cases. These complications include: Recurrent urinary tract infections with pyelonephritis; non functioning of one or both kidney units; Urinary lithiasis and the uretero-ureteral reflux secondary to retrograde ureteral peristalsis. Finally, the surgical treatment of the uretero-ureteral reflux depends on the clinical and radiological symptoms of the patients. Heminephrectomy in case of a non functioning renal segment. Excision of one ureteral segment converting an incomplete ureteral duplication into a bifid pelvis. Conversion of an incomplete duplication into a complete ureteral duplication if the common segment is near the bladder. Nephroureterectomy should be considered in case of non functioning kidney with type IV vesico-ureteral reflux.

To evaluate sensitivity and specificity of ultrasound in detecting urinary calculus in renal colic, a prospective study of 31 patients examined by both ultrasound and intravenous urography (IVU) was undertaken. Of the 27 cases of renal colic proved by IVU and/or recovery of a calculus, ultrasound correctly diagnosed urinary calculus in 26 cases with a sensitivity of 96.3%. In the 4 cases in which the sonographic examination demonstrated neither calculi nor unilateral obstruction, further evaluation confirmed the absence of calculi. Specificity of ultrasound was 100%. The results of this study support the use of ultrasound in detecting renal calculus and point out the important place of ultrasound in initial evaluation of renal colic.

We report the results of extracorporeal piezoelectric lithotripsy of gallbladder stones, using the EDAP LT 01 device, in 60 patients treated without anaesthesia or analgesia. Fragmentation was satisfactory (i.e. with fragments less than 5 mm wide) in 31 patients (52 per cent) after multiple sessions (mean: 1.6). The satisfactory fragmentation rate was higher in patients with stones smaller than 20 mm (63 vs 8 per cent; P less than 0.01) and not different in patients with solitary or multiple stones (53 vs 50 per cent). After bile acid dissolution treatment during 3, 6 and 12 months, the stone-free rates were 23, 41 and 64 per cent respectively, and significantly better at 3 and 6 months in patients with satisfactory fragmentation (42 vs 4 per cent; P less than 0.05, and 71 vs 9 per cent; P less than 0.01). Fourteen patients (23 per cent) reported biliary colic, but only one required cholecystectomy. No severe complication was observed. Piezoelectric lithotripsy is safe, requires short hospitalization and gives interesting results when the stones are less than 20 mm wide.

Retroperitoneal fibrosis occurred in a 62-year-old man who had been treated during 4 years eye-drops containing timolol. The disease was diagnosed after a sudden episode of nephritic colic. The recovery was progressive and uneventful. No corticosteroid therapy was used. Six months later the patient remained free of symptoms. Although an idiopathic origin could not be excluded, the causal relationship with timolol treatment is likely due to the chronology of events and the lack of other causes.

The development of urinary lithiasis as a result of parathyroid lesions is not an exceptional occurrence and should be routinely looked for. Among the 30 cases of parathyroid adenoma identified during a 25-year period in a department of urology in a medium-sized town, 18 were detected following the occurrence of urinary lithiasis. Clinical features in these 18 cases, as well as the investigations that led to the discovery of the adenoma are reported. The surgical cervicotomy technique used by the same operators is briefly described. In other countries (Germany, Switzerland, Italy), the detection and management of parathyroid adenomas is often considered as within the field of urology.

The results obtained in 143 cases or ureteral stones treated by EDAP LT-01 were analysed concerning stone location, ureteral manipulation, and treatment position. The ureter was divided into six segments: ureteropelvic junction (UPJ), proximal ureter higher than the lower pole of the kidney (PU1), proximal ureter between the lower pole and the iliac crest (PU2), mid-ureter between the iliac crest and the lower end of the sacroiliac joint (MU), distal ureter between the lower end of the sacroiliac joint and the ischial spine (DU1), and the distal ureter below the ischial spine to the meatus (DU2). The overall fragmentation rate (FR) was 72%, as detailed below: (table; see text) Anesthesia or iv sedation was never used for EPL. 28% of the patients underwent retrograde ureteral manipulation (29/103). For PU1, the FR was twice as high after retrograde manipulation (push back/in situ = 5/8). For UPJ, the supine position was most common. For PU1 and PU2, it was often better to have the patient lie on his side. For DU1 and DU2, a prone position was necessary. For all stones in DU1, the bladder had to be well filled and the FR was higher in DU2 than in DU1. DU2 stones appeared to adhere to the bladder wall or were intravesical (stone in the meatus). The stone-free rate for successfully manipulated ureteral calculi (3 month follow-up) is 93% (27/29). The stone-free rate for in situ stones at 3 months is 94% (70/74). Extracorporeal piezoelectric lithotripsy combined with stone manipulation is highly efficient in the management of UPJ, PU1 and DU2 stones.(ABSTRACT TRUNCATED AT 250 WORDS)

Parapyelic cysts present particular characteristics in relation to cystic disease of the kidney. Their intrasinusal development in contact with vascular and canalar elements of the renal hilum explains their often explosive symptomatology and the frequent need for surgical excision of the cyst--procedure difficult to accomplish and nearly always incomplete. Four cases are reported, including 2 with cysts communicating with excretory pathways, and symptoms, signs and diagnostic and therapeutic aspects discussed. Arguments are in favor of an acquired pathogenicity of these cysts (communication with excretory pathways, contingent presence of smooth muscle fibres in the cyst wall).

The authors relate one case of obstruction by emboly in the renal artery. The diagnosis were too late for conservative surgery. In this case, they insist on the particulary signs of that nephretic colic and they show the diagnosis measures which are able to permit a conservative surgery in urgency.
