The diagnosis of urolithiasis during pregnancy is common, even though no additional measures are required in asymptomatic cases. The present manuscript aim to review the current knowledge concerning this subject and present authors personal experience. Key words: lithotripsy; nephrolithiasis; pregnancy complications; pregnancy trimesters; uretero-lithiasis; urolithiasis. This paper aims to review this issue in the light of current knowledge. During pregnancy there are physiological and anatomical changes to the urinary tract.
The kidneys are cranially displaced by the fetus, besides increasing by about one centimeter in size, due to the increase in kidney vascularization and interstitial space during pregnancy. Hydronephrosis increases urinary stasis, acting as a major risk factor for nephrolithiasis as well as urinary infections.
Regarding lithogenic urinary parameters, the changes occur in differing directions. On the one hand, there is hypercalciuria due to increased glomerular filtration of calcium associated with the intestinal hyper-absorption of calcium by the placental production of 1, OH 2 vitamin D. In contrast, there is significant increase in urinary pH, renal excretion of citrate, magnesium, uromodulins, nephrocalcin and glycoproteins during pregnancy - inhibitory factors of urinary crystallization and formation of stones.
Such changes in opposite directions lead to a different situation from that found in non-pregnant patients. Although many factors inhibitory to the urinary-crystallization are increased, hypercalciuria in pregnant women is associated with increased urinary pH, favoring urinary supersaturation by brushite and calcium phosphate stone formation, especially carbapatite.
Having symptomatic kidney stones during pregnancy raises additional concerns because, besides all the suffering and risks it can bring to pregnant women, it is also associated with a further significant Feel my pee in the risk of premature membrane rupture 8 and increased risk of preterm labor in 1.
The pain is not directly caused by the stones themselves, but it arises from distention of the urinary tract and kidney capsule. There may be hematuria, urinary and other symptoms such as pollakiuria and dysuria, particularly when the stone is found in the distal portion of the ureter.
Nausea and vomiting may occur due to intense pain. We have to bear in mind that the drugs to be used should be selected taking into account their effects, side effects and safety of use during pregnancy, as per shown on Table 1. A: Controlled studies did not show risk; B: Improbable risk; C: Risk cannot be ruled out; D: Positive evidence of risk maternal benefit may overcome the fetal risk when in a death risk condition ; X: Contraindicated in pregnancy evidence of fetal damage ; N: Drug not classified by the FDA.
Upon clinical suspicion of renal colic or abdominal pain in pregnant women, one must perform additional tests to confirm the diagnosis. In addition to other differential diagnoses of acute abdomen and obstetric conditions, one should take into account the possibility of other urological disorders.
Initially, one should obtain urine sample for urinalysis and urine culture. Usually, in the context of renal colic, one can see microscopic hematuria, observed in Additional tests may bring relevant information, especially serum creatinine, to estimate kidney function and CBC to assess possible evidence of systemic infection. Although non-contrast abdomen CT scan is considered the gold standard in evaluating an individual with renal colic, this image scan should be avoided during pregnancy, especially in the first quarter - because of teratogenesis risks associated with radiation exposure.
MRI is mentioned in Free power point templates and nurses literature as an alternative for the diagnosis of changes in the urinary tract during pregnancy.
Another alternative for women in the second and third quarters is CT scan with lower radiation doses. Examinations performed with less radiation produce images with worse resolution, but in suspicious cases, these images may aid in the diagnosis of women in the last quarters of pregnancies. After analgesia and clinical compensation for the pregnant women with suspected renal colic, one should establish the therapeutic strategy. In this situation, one should rule out situations that would determine immediate action, namely:.
Acute kidney failure, usually associated with bilateral obstruction or in women with a single kidney. If none of these conditions are present, these pregnant women should receive drug treatment as the first choice.
Among the medications commonly used to increase the rate of ureteral stones clearance, we stress alpha-blockers and calcium channel blockers. Kidney unit clearance through the implantation of a double J-type ureteral catheter. Percutaneous renal surgery - rarely used, situations of exception. Traditionally, the procedures performed in this context aim to simply clear the kidney, either by percutaneous nephrostomy or double J-catheter.
According to a meta-analysis published inalthough the experience reported in the medical literature is relatively small - cases - ureteroscopic treatment of stones during pregnancy is safe and efficient.
In one Kidney stone for pregnant women the cases, fluoroscopy was used minimally to confirm the position of the guide wire and the double-J catheter due to a tortuous ureter, and in one case it was necessary to perform percutaneous renal access due to impossibility of access, as well as passing the guide wire in a 1. With the goal of avoiding the use of fluoroscopy, it is also possible to employ intraoperative ultrasound as a means of guiding the ureteroscopy.
Both the laser and the ballistic lithotripters have been proven safe as a source of energy for breaking ureteral stones. During anesthesia for obstetric surgery in pregnant women in ureterolithotripsy, one should consider important aspects for both maternal and fetal safety, taking into account the physiological changes of pregnancy.
Teratogenic drugs should be avoided, avoid fetal hypoxia and prevent premature labor, regardless of the technique used. Despite the lack of randomized, prospective studies, there seems to be similar safety between regional anesthesia spinal or epidural versus general anesthesia.
In both techniques, one should avoid hypotension, prevent tracheal aspiration and move the uterus to the left, ensuring adequate oxygenation, normocarbia and euglycemia.
One must also keep adequate postoperative care, including satisfactory analgesia, early ambulation, monitoring fetal heart rate and uterine contractions.
In the first trimester of pregnancy, the main fetal concerns are abortion and teratogenesis. In the third quarter the main concern is with preterm delivery. Whenever possible, we try to postpone surgery to the second quarter in women with gestational age less than 20 weeks.
When surgery is unavoidable, regional anesthesia is the first choice, thus avoiding the use of nitrous oxide. Fetal heart rate monitoring should be performed before and after surgery. Fetal heart rate and uterine activity should also be monitored during surgery. Nephrolithiasis in pregnant women did not prove to be a risk factor for the occurrence malformations in a second study that evaluated 22, Kidney stone for pregnant women or fetuses with congenital malformations.
The approach to these patients is challenging from diagnosis to therapy decisions, as well as in obstetric care. It is essential to have a multidisciplinary approach Horny mommas Kidney stone for pregnant women care and eventually tocolytic agents.
In conclusion, urolithiasis and complications occur with relatively high frequency during A loser for loving. The recognition of this disease, its complications and peculiarities during pregnancy is of Kidney stone for pregnant women importance to the obstetrician, urologist, nephrologist and all professionals involved in the care for pregnant women.

Jun 18, · Kidney stones are commonly detected during the third trimester of pregnancy. Pregnant women with kidney stones are more likely to have a history of hypertension and renal diseases. Kidney stones during pregnancy pose an increased risk of miscarriage, preeclampsia, gestational diabetes mellitus and C-section deliveries. Kidney or ureter stones in pregnancy are a major health concern and are one of the most common causes for abdominal pain in pregnant women. Stones may lead to a blocked kidney, kidney infection which may spread to the whole body, and early labour which needs immediate hospital attendance and treatment for the expecting mother. Im 11weeks pregnant and recently had my first encounter with kidney stones.

The approach to these patients is challenging from diagnosis to therapy decisions, as well as in obstetric care. Obstet Med. Where ultrasound has failed to diagnose stones, and symptoms such as fever, vomiting, and pain are persistent, or there is deteriorating renal function, alternative diagnostic procedures may be considered. J Reprod Med ; Significant advances have been made in endourology over the last decade. PCNL involves creating an access tract into the renal collecting system through which a nephroscope can be introduced Figure 3. It has little periureteral thermal effect and does not result in energy transmission to the fetus. Iodinated and gadolinium-based contrast agents also cross the placenta, so may affect the fetus.

Changes during pregnancy that impact stone formation include:. Common symptoms of a kidney stone during pregnancy include:.
Along with the other challenges faced by women while they are pregnant, you can add the risk of developing a kidney stone. The end result is that the rate of stone formation during pregnancy actually appears similar to the rate in non-pregnant women and has been estimated to occur in 1 in pregnancies. When do stones present during pregnancy and what are the chances of spontaneous passage? Researchers in France have recently compared pregnant women who formed stones with 5, non-pregnant female stone formers Meria and coworkers.
