Yuma Nurse Practitioner Explains Kidney Stone Symptoms, When to Seek Emergency Care
ECH nurse practitioner Mitzi Pacheco breaks down which kidney stone symptoms can wait and which ones send you straight to the emergency room.

Mitzi Pacheco, a nurse practitioner at Exceptional Community Hospital in Yuma, puts kidney stone pain in stark terms: many patients describe it as one of the most intense experiences of their lives. With Yuma County temperatures running unseasonably high this March, she is urging residents to recognize the warning signs early and understand exactly when that pain crosses into emergency territory.
Pacheco laid out the full clinical picture on KYMA's Medical Minutes, the ongoing health education series that brings local clinicians directly to Yuma County audiences. Her guidance covers how stones form, what they feel like, what to do at home, and when to stop waiting and go straight to Exceptional Community Hospital's emergency department.
How kidney stones form in the Desert Southwest
Kidney stones develop when minerals in urine concentrate to the point where they crystallize and bind together inside the kidney. In the Desert Southwest, the environment accelerates that process considerably. High ambient temperatures drive fluid loss through sweat, and when fluid intake doesn't keep pace, urine becomes more concentrated and the threshold for crystallization drops. For Yuma County residents, that means the heat is not just uncomfortable; it is a direct physiological risk factor for stone formation.
The most common stone type is calcium-oxalate, formed when calcium and oxalate bind in concentrated urine. Diet and metabolism both influence who develops stones and how often, which is why the clinical management of recurrent stone formers goes well beyond a reminder to drink more water.
Recognizing the symptoms
A stone sitting still inside the kidney may produce no symptoms at all. The severe pain most patients know kicks in when the stone begins to migrate, specifically when it moves from the kidney into the ureter, the narrow tube that drains urine into the bladder. That transition is when the ureter contracts around the stone and generates the intense, wave-like pain known as renal colic. It is also when most patients present for emergency care.
Pacheco describes the full symptom profile as:
- Sharp pain in the flank or back, sometimes radiating toward the groin or lower abdomen
- Nausea and vomiting
- Hematuria, meaning blood in the urine, which can range from microscopic to visibly pink or red-tinged
Not every patient experiences every symptom, but flank pain combined with any of the others warrants at minimum a call to a provider.
When to go to the emergency room
Pacheco is explicit about which symptoms require immediate medical evaluation rather than a wait-and-see approach. Go directly to Exceptional Community Hospital or call 911 for:
- Uncontrolled pain that cannot be managed with over-the-counter medication
- Inability to pass urine
- Fever or chills
- Any other signs of infection
The urgency behind that list comes down to one dangerous combination: an obstructing stone paired with infection. When a stone blocks urine flow and bacteria are present, infection can back up into the kidney and reach the bloodstream rapidly, escalating into a life-threatening emergency within hours. Fever or chills alongside kidney stone pain is not a symptom to monitor from home.
Managing a stone without red-flag symptoms
For patients who have kidney stone symptoms but none of the emergency warning signs above, the clinical approach centers on supportive care and close monitoring. Pacheco's guidance for this group covers three concurrent priorities:
- Pain control: Over-the-counter anti-inflammatory medications can manage mild to moderate renal colic for many patients. A provider can evaluate whether prescription-strength analgesics are appropriate based on pain severity.
- Increased hydration: Drinking adequate fluids, provided there is no medical reason to restrict intake, helps move a stone through the urinary tract while diluting urine to slow further crystallization. In Yuma's heat, baseline hydration is already a challenge; during a stone episode, maintaining fluid intake becomes even more critical.
- Imaging and follow-up: A CT scan or ultrasound can pinpoint the stone's exact size and location, which drives all subsequent treatment decisions. Small stones, generally under about five millimeters, often pass on their own with conservative measures. Larger stones are far less likely to clear without intervention, which is where urology referral enters the picture.
When a stone requires procedural treatment, two approaches are most common. Lithotripsy uses focused shock waves to break the stone into smaller fragments that can pass through the urinary tract naturally. Ureteroscopy is a minimally invasive procedure in which a thin scope is passed through the urethra and bladder into the ureter to locate and remove or fragment the stone directly. The appropriate choice depends on stone size, composition, and position, decisions a urologist makes after reviewing imaging.
Prevention starts with hydration
For anyone living in the Sonoran Desert, Pacheco's prevention message is straightforward: drink more water than you think you need, and increase intake further during hot weather. Concentrated urine is the shared risk factor across most stone types, making consistent, adequate hydration the single most effective tool for reducing recurrence.
For people specifically prone to calcium-oxalate stones, targeted dietary adjustments reduce risk further:
- Moderate high-oxalate foods such as spinach, nuts, and chocolate
- Reduce dietary sodium, since high sodium intake raises calcium excretion in the urine, increasing crystallization risk
- Maintain adequate calcium intake from food sources, which helps bind oxalate in the gut before it reaches the kidneys
Recurrent stone formers benefit from a metabolic evaluation: a blood and urine workup that identifies the underlying drivers of stone formation. That workup allows providers to build a prevention strategy tailored to each patient's specific chemistry rather than relying on generic advice.
Local resources and follow-up care
Exceptional Community Hospital handles acute presentations, providing emergency evaluation and imaging for patients in active distress. Primary care clinics throughout Yuma County manage follow-up care, imaging referrals, and metabolic workups for patients navigating their first stone or dealing with recurrent episodes. Pacheco encourages engaging that local clinical infrastructure early, before symptoms escalate.
Practicing medicine in the Desert Southwest gives Yuma's clinicians a specific, environment-informed perspective on kidney stone risk that general guidance doesn't always capture. Anyone who experiences a first episode should treat it as a prompt to establish care, get imaging, and have a prevention conversation with their provider before the next one.
