Hi. I have had a few blood tests recently and I am wondering if I should be concerned with a GFR of 88? I am a 35 year old female. Also is bilateral hydronephrosis hereditary? Can an adult have it and not know it?

The normal value for an estimated glomerular filtration rate (eGFR) is greater than 60 milliliters per minute per 1.73 meters squared. Hence, your eGFR is normal. It is possible to have bilateral hydronephrosis and have it discovered incidentally during a … Continue reading

My 17 year old daughter started having severe kidney pain a few months ago. After a CT scan and ultrasound, they found she had hydronephrosis of her left kidney, but they didn’t see any stones. Last week she had a follow up ultrasound, and now there is hydronephrosis in both kidneys. They said there was Pelviectasis and slight central caliectasis in her left kidney. She is an active teenager, watches her diet closely, doesn’t eat sugar or anything unhealthy. Her kidney and liver function tests came back normal. We have a family history of Diabetes, but I haven’t found any other family history of kidney disease. What do I do from here? Is there anything I should have them test for? I’m really worried about her, and don’t want her to have permanent kidney damage.

The problem that you describe is a urological problem. This should be evaluated by a urologist. A urologist is a surgeon and deals with surgical evaluation and treatment of the urinary tract. I am a nephrologist and have no surgical … Continue reading

Hello, I am a 44 year old male that is a kidney patient with history of s/p pyeloplasty other; hydronephrosis unspecified type. I just had a CT Abdomen and pelvis without contrast on July 6, 2021. A follow-up to a previous UPJ obstruction Robot assisted laparoscopic left pyeloplasty, cystoscopy, left ureteral stent placement procedure. The follow up findings were: Split function 77.35% on the right and 22.65% on the left. Left kidney demonstrates moderate to severe pelvocaliectasis with severe cortical thinning. Compared with previous 09/2020 CT, it appears to have decreased in severity. No renal or ureteral calculus. Mild right not significantly change compared to 09/2020. My question is what is next? What is my doctor’s next move? What would you do next, if you were my doctor? Please tell me if there’s a light at the end of the tunnel!! Thanks in advance for your response.

I have been having some periodic pains in backside of lower ribs, nausea and some little form of difficulty in breathing. Could it be kidney problems?

Pain is a very unusual way for kidney disease to present. Kidney disease can present with pain in cases of kidney stone disease, blockage of the kidney, infection or bleeding but these are very intense pains that do not come … Continue reading

Dear Sir, my urine output is from 4000 ml everyday. Doctors here say the problem is blockage and back fire of urine towards kidney. The urine is not properly out from kidney to bladder. Ultrasound shows the size of kidneys and position as normal. Only mild to moderate hydronephrosis is seen. Other things are normal. No mass or cyst seen; right kidney measures 10.0 cm, left kidney measures 9.5 cm. Both kidneys appear echogenic. Both kidneys are normal in size, shape, and position. Outline is smooth and well demarcated. Cortical thickness of right kidney measures 0.8cm.; the left kidney measures 0.8 cm. Urinary bladder shows thick and irregular walls. Wall thickness measures 1.4 cm. Please suggest proper treatment. Thanks and Regards.

Hi, last October I had bilateral kidney stents fitted when my eGFR was at 25. It increased to 30 but has since dropped back down. The urologist wants to remove the stents as kidney function hasn’t improved. Is 4 months long enough for improvement? I would like to keep the stents as the pain which was unbelievably bad is so much better – could this be the stents? I am a 34 year old female, the kidney trouble started after my third child in 2019. Thanks for taking the time to read this.

I am unable to make a specific diagnosis based on the information that you present. If the obstruction has been completely resolved, then the kidney function should improve and four months is a sufficient time for this to improve. However, … Continue reading

My recent ultrasound on the kidney revealed light hydronephrosis and the radiologist suggest CT urogram. But since I had an adverse reaction to CT radiation from last nine years ago, I intend to suggest to my family MD to prescribe MRI of kidney and ureters (my cystoscopy was normal just recently done). Can the MRI be a good substitute for what the CT can do?

Good morning Doctor. Yesterday I had back pain through my left hip to my leg. This pain didn’t allow me to turn, sit or walk. I was never admitted to the hospital but at public clinic they recognized I had a problem and didn’t do anything about it. Is it the kidneys?

My 12 week old son has hydronephrosis. When he was born he had an ultrasound which showed the right kidney to be mildly dilated at 6mm. The consultant at the time said this was nothing to worry about and wouldn’t warrant antibiotics and to have a review ultrasound at 12 weeks old. My son had this scan today and it showed the right one has become more dilated. I am now worried in the last 3 months of being untreated this has caused damage. And should my son have been put on the antibiotics as a preventative measure? The consultant said they only prescribe antibiotics if the dilation was more than 7mm. To me a mm difference is too risky to leave. Thank you.

I am an adult nephrologist and do not have any expertise in children or infants. A pediatric urologist would be the best person to consult about this issue. A urologist deals with diseases of the urinary tract including hydronephrosis.

What does the following mean? The Lasix renogram was performed using 40 mg of Lasix at 15 minutes. Kidneys: The radionuclide angiographic images demonstrate mildly decreased perfusion to the right kidney compared with the left kidney. The nephrographic images demonstrate a small right kidney with tracer excretion into the renal collecting system with pelviectasis. Normal tracer excretion into the left renal collecting system without hydronephrosis. Symmetrical tracer activity in both ureters. Tracer activity is present in the bladder. Left renal function: 68 % at 2 to 3 minutes. Right renal function: 32 % at 2 to 3 minutes. Post Lasix Left Kidney: T1/2 is 9.5 minutes after Lasix. Post Lasix Right kidney: T1/2 is 4.8 minutes after Lasix. Other findings: Normal T-1/2 lasix is 20 minutes. IMPRESSION: 1.) Small right kidney with pelviectasis. 2.) Split function is 68% for the left kidney and 32% for the right kidney.

This kidney scan suggests that there may be a blockage in the right kidney and the right kidney is smaller than the left. This should be evaluated by a urologist to see what further testing and treatment may be needed. … Continue reading
