The placement of a double J stent?


My father has been experiencing persistent lower back pain since the placement of double J stents for kidney stones.
Initially, he also had a low-grade fever.
He went to the emergency room to confirm the position of the stents and was prescribed antibiotics.
Although his temperature has stabilized, the lower back pain continues, and recently (in the second week), he has been experiencing abdominal pain after urination, requiring pain relief medication.
Is this normal?
Additionally, he has seen a urologist and is currently taking medication for benign prostatic hyperplasia, which has a side effect of orthostatic hypotension.
My father has a history of hypertension, but since starting this medication, his systolic blood pressure has dropped to 100-110 and diastolic to 70-80.
We are hesitant to give him his original antihypertensive medication.
He has been frequently complaining of loss of appetite, food tasting bland, and low energy.
Could this be related to his low blood pressure? Thank you!

Hello: Having a double J stent can cause discomfort, urinary symptoms, and hematuria, but it should not cause a fever.
If a fever persists, seek medical attention.
If blood pressure is between 100-110/70-80, there is no need to increase blood pressure medication.
Regarding poor appetite, medication can be adjusted during the follow-up visit, as some medications may cause gastrointestinal symptoms.
Wishing you good health.

More Info


After undergoing a procedure involving the placement of a double J stent, it is not uncommon for patients to experience discomfort or pain in the lower back and abdominal regions. This can be attributed to several factors related to the procedure and the stent itself. The stent is designed to keep the ureter open, allowing urine to flow from the kidney to the bladder, but its presence can sometimes lead to irritation or inflammation in the surrounding tissues.
The persistent lower back pain your father is experiencing could be due to irritation from the stent, especially if he has a history of urinary tract issues or kidney stones. Additionally, the fact that he had a low-grade fever initially suggests that there may have been some inflammation or infection, which can also contribute to discomfort. It is good that he had the stent's position confirmed and was treated with antibiotics, as this helps rule out any significant complications such as an infection or obstruction.

Regarding the abdominal pain he experiences after urination, this could be related to bladder spasms or irritation caused by the stent. It is not unusual for patients with stents to experience some degree of urinary discomfort, including urgency, frequency, or pain during urination. If the pain is severe or worsening, it is essential to follow up with his urologist for further evaluation.

As for the low blood pressure and the side effects of the medication for benign prostatic hyperplasia (BPH), it is crucial to monitor his blood pressure closely. The medication can indeed cause orthostatic hypotension, which is a drop in blood pressure upon standing, leading to symptoms such as dizziness or fainting. Since your father has a history of hypertension, the adjustment in his blood pressure medication may be necessary to avoid excessively low readings.
His current blood pressure readings of 100-110 systolic and 70-80 diastolic are on the lower end of the normal range, especially for someone with a history of hypertension. This could explain his complaints of decreased appetite and fatigue, as low blood pressure can lead to inadequate blood flow to vital organs, resulting in symptoms like weakness and lack of energy. It is essential to consult with his healthcare provider about these symptoms and the appropriateness of his current medication regimen.
In summary, while some discomfort and low-grade fever can be expected after the placement of a double J stent, persistent pain and low blood pressure warrant further investigation. It is advisable to maintain open communication with his healthcare providers to ensure that his symptoms are adequately managed and to adjust his medications as necessary to maintain optimal blood pressure levels. Regular follow-ups and monitoring are crucial in managing his overall health and addressing any complications that may arise from the stent placement or his medications.
