Kidney Stones: Surgical Options and Safety Concerns - Urology

More Info

---

When it comes to managing kidney stones, particularly in the case of your father who has been diagnosed with a left ureteral stone causing hydronephrosis, surgical intervention is often necessary. The proposed treatment involves ureteroscopy to remove the stone and the placement of a double-J stent (J-stent) to facilitate urine flow and prevent complications during the healing process. Additionally, the right kidney stone will be treated with extracorporeal shock wave lithotripsy (ESWL) at a later date.


Safety of the Procedures
Both ureteroscopy and ESWL are generally considered safe procedures with a low complication rate. Ureteroscopy involves the use of a thin tube with a camera (ureteroscope) to visualize and remove the stone. This method is minimally invasive, meaning there are no large incisions, which significantly reduces the risk of infection associated with open surgery. The most common complications include:
1. Urinary Tract Infection (UTI): While the risk is present, it is relatively low. Prophylactic antibiotics are often administered to minimize this risk.

2. Bleeding: Some patients may experience hematuria (blood in urine) post-procedure, but this typically resolves on its own.

3. Ureteral Injury: Though rare, there is a slight risk of injury to the ureter during the procedure.

Extracorporeal shock wave lithotripsy (ESWL) is also a safe procedure, where shock waves are used to break the stone into smaller pieces that can be passed more easily. Complications can include:
1. Bruising or Pain: Patients may experience discomfort or bruising in the back or abdomen.

2. Incomplete Stone Clearance: In some cases, fragments may remain, necessitating further treatment.

3. Kidney Damage: Although rare, there is a potential risk of damage to the kidney tissue.


Impact on Sexual Function and Future Kidney Health
Regarding concerns about sexual function, neither ureteroscopy nor ESWL typically affects sexual health. These procedures are focused on the urinary tract and should not interfere with erectile function or libido.
As for the concern about future kidney health, if the stones are effectively treated and the underlying causes are managed (such as hydration and dietary modifications), the likelihood of requiring dialysis in the future is minimal. However, if kidney function is severely compromised due to prolonged obstruction or recurrent stones, there could be a risk of chronic kidney disease. Regular follow-up and monitoring of kidney function are essential.


Pain and Discomfort from the J-Stent
The placement of a double-J stent can cause some discomfort, including:
- Frequent Urination: Patients often report increased urgency and frequency of urination.

- Dysuria: Painful urination may occur.

- Back Pain: Some patients experience discomfort in the flank area where the stent is placed.

These symptoms are usually temporary and should improve once the stent is removed, which is typically done after a few days to weeks, depending on the individual case.


Conclusion
In summary, the surgical options for treating kidney stones, including ureteroscopy and ESWL, are generally safe and effective. While there are risks associated with these procedures, they are relatively low, and the benefits of removing the stones and preventing further complications outweigh these risks. It is crucial to maintain open communication with the healthcare team, address any concerns, and follow post-operative care instructions to ensure a smooth recovery. Additionally, lifestyle modifications, including increased fluid intake and dietary adjustments, can help prevent future stone formation.
