Outpatient removal of a temporary double J stent (DJ) usually takes place two to four weeks after kidney stone treatment, while discomfort lasts between a few days and the entire time the tube stays in place. Flank aching occurs during urination as bladder pressure travels backward to the kidney, easing with steady daytime hydration and avoiding holding urine.
Kidney stone: sharp pain as it moves down; small stones often pass with fluids.
Why does a double J stent (DJ) cause flank pain during urination?
A double J stent (DJ) is a thin, flexible hollow coil placed inside the ureter (a temporary internal drainage tube placed between the kidney and bladder). Both ends of the plastic tube curl into soft loops: the upper loop rests inside the renal pelvis of the kidney, and the lower loop rests inside the urinary bladder. In my urology clinic, I explain to patients that this back-pressure is the mechanical reason behind flank soreness, as the tube splints the ureter while post-surgical swelling subsides.
Flank aching happens because the hollow tube functions as an open channel between organs. When you void, your bladder muscle contracts firmly to expel urine through the urethra. Because the tube contains multiple drainage holes and an open core, a portion of that muscular pressure travels upward directly into the kidney. This back-pressure temporarily distends the renal capsule, causing an ache or cramp in your flank that peaks during urination and settles within two minutes after voiding.
The lower loop of the tube rests directly against the trigone, the sensitive nerve-rich base of the urinary bladder. Mechanical contact on the trigone stimulates local nerve endings, signalling to your brain that the bladder is full and provoking frequent washroom visits. Bodily movement such as walking or stair climbing also causes the smooth plastic to rub against delicate mucosal capillaries, producing pink-tinted urine. I remind patients that pink-tinted urine after walking is an expected mechanical event. Why some individuals experience sharp spasms while others feel only mild heaviness remains an area where individual nerve sensitivity differs. Discomfort typically stabilizes into a steady baseline after the first three days.
What home steps help relieve double J tube discomfort (DJ)?
Practical relief starts with steady fluid intake spread evenly across daytime hours. Drinking two to three litres of clean water daily keeps urine dilute and pale straw-coloured. Concentrated acidic urine irritates the sensitive bladder lining, triggering sharper muscular spasms against the lower loop. Spreading your fluid intake prevents sudden bladder distension, although consuming large volumes of water immediately before bedtime should be avoided to prevent repeated nocturnal awakenings.
You should also void promptly whenever you sense urinary urgency, as holding urine elevates bladder pressure and increases backward reflux toward the kidney. Placing a warm heating pad or warm water bag over the lower abdomen relaxes the pelvic floor musculature. For pain relief, take the bladder-soothing medicine or supportive pain relief your doctor advises at discharge. Heavy weightlifting, strenuous workouts, and traveling over bumpy roads on two-wheelers should be paused until the tube is removed.
Last month, an office clerk from Ahinsa Khand II in Indirapuram came to my clinic three days after stone treatment, worried because his urine looked pink. Fearing that bleeding meant internal damage, he had drastically cut down his water intake to half a litre, which concentrated his urine and worsened his bladder spasms. Once I examined him and reassured him to resume drinking regular water, his urine cleared to pale straw and his cramps eased by evening.
During follow-up OPD consultations, I examine the flank for tenderness, review temperature records, and assess urine testing. We check urine culture and kidney function in the hospital lab to verify that no infection is developing and that filtration remains healthy. Normal serum creatinine levels confirm that both kidneys continue draining effectively.
How does outpatient double J stent (DJ) removal work in clinic?
Removal is scheduled once the treated ureter has healed, usually between fourteen and twenty-eight days following stone fragmentation. Leaving a temporary double J stent (DJ) in place beyond its scheduled date allows mineral salts in urine to deposit along the plastic surface. Over several months, heavy encrustation can anchor the coils to tissue, causing chronic blockage and severe infection that requires complex endoscopic procedures to break the crusts before extraction. Timely extraction protects long-term renal function.
The extraction procedure takes place in an outpatient procedural room without requiring general anaesthesia or overnight hospital admission. A urologist instils local anaesthetic jelly into the urethra, introduces a slender flexible cystoscope, grasps the lower coil, and gently withdraws the tube. The procedure takes under two minutes. Mild urethral stinging during urination may persist for twenty-four hours after the procedure.
What does Healing Tree do for double J stent (DJ) care?
At Healing Tree Hospital in Indirapuram, our urologists perform DJ stent placement and removal as day-care procedures. When stones lodge in the urinary tract, our surgical team carries out ureteroscopy (URS) for ureteric stones, with DJ stenting to ensure uninterrupted urine drainage while tissues heal. If discomfort persists or stone clearance requires verification before removal, we conduct kidney and bladder (KUB) ultrasound and CT of the abdomen on campus. To monitor kidney health and ensure the urinary tract remains sterile, we check urine culture, PSA and kidney function in the hospital lab. Patients can consult our specialists in the urology department.
When does flank pain after stone treatment become an emergency (DJ)?
Mild flank aching during voiding and pink urine are expected, but specific red flags demand immediate hospital evaluation. Seek urgent emergency care if you develop a high fever accompanied by chills or shaking rigors, which points to an ascending kidney infection. Continuous severe flank pain that does not ease, passing dark red urine containing thick blood clots, or sudden inability to pass urine also indicate an acute problem.
If you experience any of these symptoms, go immediately to the emergency department at Healing Tree Hospital, 30/1, Shakti Khand III, Indirapuram, where an emergency doctor and urologist are available round the clock, or call +91 92891 30163.
