Navigating the Path Forward with Newborn Hydronephrosis
I'm seeking sincere and practical insights regarding the various risks associated with the circumstances we are currently encountering. At 37 weeks along with my pregnancy, I am expecting a son. At 30 years old, I'm married and maintain good health, free from any medications or prior health concerns. I neither smoke, drink, nor vape, and my pregnancy has been relatively smooth apart from this recent finding. This is my third pregnancy overall, and I have one living child. I previously experienced a spontaneous early miscarriage last November, which did not necessitate any medical intervention. Now, to the matter at hand— During an ultrasound at 34 weeks and one day, an enlargement of the baby's right kidney was detected, measuring 9mm and diagnosed as mild pyelectasis. Consequently, I was referred to Maternal-Fetal Medicine (MFM). At 37 weeks and one day, MFM conducted another anatomy ultrasound. By this time, both the right kidney and ureter were noted to be enlarged, specifically the kidney at 8.1mm, and classified as moderate to severe pyelectasis. Following this, I had an appointment with a urologist at 37 weeks and three days. He assessed the condition as moderate hydronephrosis and proposed the following recommendations: - Circumcision (which we strongly oppose based on our beliefs). - Commence a low dose of amoxicillin immediately after birth, until it is confirmed that there is no reflux, or the issue resolves on its own if it is reflux. - An ultrasound scheduled 48 hours post-delivery. - Should hydronephrosis still be detected (something the urologist anticipates), a return visit to urology will be necessary to check for reflux. - If reflux isn't the problem, around one month after birth, a test will be needed to see if there’s an obstruction in the urinary tract. Alternatively, if we choose to forgo these procedures and prefer a more observational approach, the urologist mentioned that regular ultrasounds would be conducted. However, he noted that the risk of developing a urinary tract infection (UTI) is “high,” though he did not clarify what that meant. I am apprehensive about placing my newborn on continuous antibiotics for a potential UTI that may or may not materialize. When I pressed him about the risks associated with the antibiotics, he claimed there were none, which I find hard to accept as an absolute truth. What are the actual risks associated with administering long-term low-dose amoxicillin to newborns? What is the likelihood of my baby developing a UTI? How dangerous is the wait-and-see strategy? Am I overreacting by perceiving this situation as overly serious? I prefer to pursue the least invasive options available—avoiding antibiotics and unnecessary tests aside from ultrasounds, given that this condition might resolve itself. Learning of this issue just three weeks before my due date has left me feeling overwhelmed, as I grapple with the significant decision between using long-term antibiotics or exposing my baby to the risk of infection. Any advice would be immensely helpful as I navigate this challenging situation.

It sounds like you are navigating a challenging situation with your newborn's diagnosis of moderate hydronephrosis and considering different approaches for managing it. It's completely understandable to feel overwhelmed, especially this close to your due date. Here’s a summary of the key points, followed by an explanation and prioritized next steps.
Key Points:
- Hydronephrosis in Newborns: This condition may resolve on its own but requires monitoring due to potential complications like urinary tract infections (UTIs).
- Antibiotics Concerns: Long-term use of antibiotics carries risks, but these must be balanced against the risk of UTI and its possible complications.
- Monitoring vs. Intervention: A watchful waiting approach is valid, especially if you prefer to avoid invasive procedures.
Explanation:
Hydronephrosis in infants can be caused by various factors, including urinary obstruction or reflux, and often resolves as the child grows. The concerns about UTI arise because hydronephrosis may lead to an increased risk of infection in the urinary tract, which can potentially escalate into more serious health issues if not monitored.
Antibiotics such as amoxicillin are used prophylactically to prevent UTIs, especially if reflux is suspected. While antibiotics are generally safe, long-term use can lead to side effects, including:
- Alteration of gut flora (which may affect digestion).
- Allergic reactions (though rare).
- Development of antibiotic-resistant bacteria, which could complicate future treatments.
Next Steps:
-
Monitor Symptoms: After birth, closely monitor your newborn for signs of infection, including fever, irritability, and changes in feeding patterns. Share any concerns with your pediatrician immediately.
-
Consider Scheduled Follow-Ups: Plan for regular ultrasounds as suggested; this non-invasive approach can provide insight into whether the hydronephrosis is improving or requires further investigation.
-
Discuss Alternatives: If UTI risk is a concern, ask your healthcare team about alternative strategies to manage potential UTIs without immediate antibiotic treatment. Depending on your baby's situation, they may recommend a "watchful waiting" plan where close observation is balanced with timely interventions if needed.
-
Educate Yourself: Seek reliable resources on hydronephrosis and UTI risks in infants. Understanding the condition better can help alleviate some concerns.
-
Communicate Concerns: Ensure you have open communication channels with your healthcare team. Don’t hesitate to bring up any specific fears about antibiotic use or the necessity of interventions. They should provide clarity and reassurance based on the latest evidence and your family’s unique values.
Your feelings are valid, and navigating this may take both patience and trust in your healthcare team. Remember, focusing on your baby's well-being and keeping engaged with health professionals will help navigate this phase effectively. Let me know if you have any other questions or need further clarity!

Blood in Urine: Seeking Guidance
A 20-year-old female weighing 140 pounds has not been taking any medications or supplements, and has no prior or current medical conditions. Her menstrual cycle last occurred two weeks ago. While at work, she observed blood in her urine, which appeared light red but darker than pink. Accompanying this symptom, she has experienced some abdominal discomfort. Notably, there was no evidence of blood on her underwear, only when she urinated. Additionally, she felt a moment of lightheadedness upon noticing the blood, which has since subsided; she attributes this feeling to her anxiety about the potential seriousness of the situation. Given these symptoms, what could be the likely cause? She is uncertain whether to visit the emergency room or to wait until urgent care is available tomorrow for a consultation. As she recently relocated and does not have a primary care physician yet, her anxiety is heightened.
Exploring Endolymphatic Hydrops: Could This Be My Condition?
34 years old / Female Current weight: 165 lbs Navigating the challenges of motherhood In early December 2025, I caught a cold. By mid-December, my right ear felt blocked, but I attributed it to the cold virus. As New Year approached, I experienced another cold, which coincided with an onset of ringing in my ears. Disturbingly, sounds started to seem altered from the affected ear, accompanied by a persistent fullness in that area. Additionally, I noticed twitching of my eye and swelling in the salivary gland on the same side. My primary care physician prescribed a decongestant and Flonase; however, because I am currently breastfeeding, I hesitated to take the medications as directed. On January 27, I was evaluated by an ear, nose, and throat specialist, who requested a hearing assessment the following day. The results indicated that I had sensorineural hearing loss affecting my low-frequency hearing range (250 Hz to 500 Hz). The doctor prescribed a steroid with the hope of addressing the issue promptly. Now on day 10 of steroid treatment, I have experienced significant relief. Remarkably, I've noticed a substantial amount of thick, putty-like mucus clearing from my nasal passages. The pressure in my ear has subsided, and sounds are returning to normal, though I still perceive a slight ringing — possibly just a touch of hearing loss remains. What concerns me is whether ongoing sinus congestion could be the root of these symptoms or if I might genuinely be dealing with endolymphatic hydrops. Notably, I have not experienced any episodes of dizziness. In the evenings, I tend to feel considerable pressure building on the right side of my head, almost as if my sinuses are becoming blocked once more. I would greatly appreciate any insights or advice on this matter, as I find myself in a state of uncertainty regarding my condition.
Experiencing Occasional Hematuria: Seeking Guidance
Greetings, medical professionals. I appreciate your assistance with the following situation. **Patient Overview:** - **Age:** 47 - **Gender:** Male - **Height:** 6 feet - **Weight:** 202 pounds **Symptoms Overview:** Approximately three months ago, I began to observe small traces of blood in my urine. It's a minimal amount, usually just a couple of drops occurring at the end of urination. I do not suffer from any pain, fever, chills, or urinary difficulties. Initially, I suspected that this could be linked to kidney stones or exercise-induced hematuria, as I maintain a rigorous exercise routine spanning two hours daily, seven days a week. My workouts alternate between strength training 3-4 times a week and cardio exercises, including rowing, treadmill use, the elliptical, stair climbing, and jump rope. After several weeks, I also observed tiny tissue-like fragments in my urine, prompting me to consult a doctor, as I suspected a urinary tract infection. Although I have an enlarged prostate, my physician considered it a benign issue, attributing the swelling to the potential chain reaction of a UTI leading to bladder infection and subsequently causing prostate inflammation. **Diagnostic Tests and Outcomes:** I underwent a comprehensive metabolic panel, which included tests for glucose, BUN, creatinine, and various electrolytes. All results fell within normal ranges, with the exception of a low BUN/creatinine ratio (8). Additionally, I received a Creatine Kinase (CPK) test, which returned normal results. A complete blood count (CBC) with differential was conducted, showing all parameters, including WBC, RBC, and hemoglobin, to be normal. Urinalysis reflected negative findings for GLU, BLO, NIT, and LEU. However, it indicated a small amount of bilirubin, a ketone level of 15, a specific gravity of 1.025, a pH of 5.5, and a protein level at 30. Uric acid levels were 8.1, within normal limits, though an inflammatory marker was mildly elevated. A sedimentation rate (Westergren) displayed a slight elevation at 19 (normal range is up to 15). A CT scan of the abdomen and pelvis with contrast yielded several findings: - **Lung Bases:** A few small pulmonary micronodules were noted, but otherwise clear. - **Liver, Spleen, and Pancreas:** All appeared normal without lesions. - **Kidneys:** Normal with no stones or masses. - **GI Tract:** The stomach was mildly distended, but otherwise normal with stool presence noted in the colon. - **Pelvis and Vascular Structures:** Solid organs and vessels appeared normal. - **Other Findings:** Prominent inguinal lymph nodes were potentially reactive, alongside a small left inguinal hernia. **Follow-Up Treatment:** Following these evaluations, my physician prescribed sulfamethoxazole for a duration of 28 days. I adhered to the regimen fully, and while undergoing treatment, all symptoms subsided completely. However, this occurred about a month ago, concluding in late December. **Current Situation:** This evening, after my workout, I noticed the return of blood traces in my urine. While I do not experience pain, I have difficulty with bowel movements, feeling persistently constipated regardless of food intake. This change coincided with a mild tearing sensation during exercise on the adductor machine. Additionally, I have developed a reddish rash on both arms, which had resolved during the antibiotic treatment but has now reappeared. Previously, this rash was effectively treated with prednisone, leaving me unsure if this is connected to my earlier symptoms. **Concerns:** I worry that standard medical tests might overlook a significant issue affecting my prostate, colon, or urinary system. My insurance policy does not cover colonoscopy or prostate evaluation, and I have been advised to consider these procedures, though they would cost nearly $7,000 out of pocket. While I understand the necessity of these assessments if needed, I prefer to seek a second opinion before committing to such expenses. It's important to note that there is a family history of cancer, primarily lung cancer. I welcome any advice or insight into my case and will provide any additional details you may require.
Gene Testing Outcomes Suggest Elevated Risk for MPN
A 27-year-old male of Irish heritage recently conducted a commercial gene analysis, and here are the findings: - **Rs12340895 (C;G)** Result Interpretation: "Doubles the likelihood of developing V617F-positive MPN." - **Rs3780374 (A;G)** Result Interpretation: "Significantly raises the probability of V617F-positive MPN manifestation." Based on my research, it appears that having these two genetic markers indicates a strong predisposition to this particular form of cancer. What steps should I consider taking to either prepare for or potentially postpone the onset of this condition? Should I discuss these findings with my healthcare provider? My studies suggest there isn’t a definitive cure for this condition.
Understanding Preseptal Cellulitis in Children
Hello everyone. I'm reaching out for assistance. My 6-year-old son recently experienced a concerning issue. He woke up on Friday with significant swelling around his eye, nearly closing it entirely. We quickly took him to the emergency room, where doctors diagnosed him with preseptal cellulitis. They prescribed antibiotics, specifically cephalosporin, as part of his treatment. However, after approximately 30 hours on the medication, I’ve noticed that his condition seems to have deteriorated. We’ve been applying warm compresses, which help reduce some swelling temporarily, but he now has a noticeable bump right in the center of the affected area. This morning, he woke up again with his eye completely shut. I’m uncertain whether I should return to the ER for further evaluation. I appreciate any advice or insights you can provide. Thank you!
