Background: Life expectancy has continuously risen worldwide. Because the elderly may tolerate complications poorly, the risks and benefits of percutaneous nephrolithotomy (PCNL) in those patients should be discussed thoroughly. Objective: To analyze utility and operative outcomes of PCNL with respect to age. Materials and Methods: A retrospective study of PCNL was performed at Ramathibodi Hospital between 2011 and 2020. The patients were divided into two age groups, 1) below 70 years old and 2) 70 years old and above. Comparison of demographics, operative data, and postoperative outcomes were analyzed. Results: Of the 253 patients, the overall stone-free rate (SFR) was 59.7%. The SFR in younger groups and older groups were 59.4% (126/212) and 61.0% (25/41), respectively, which was not significantly different (p=0.999). There was a similar in-stone burden between the two groups (p=0.573). Patients in the older group had worse renal function, higher American Society of Anesthesiologists score, and more comorbidities, including hypertension and ischemic heart disease. However, estimated blood loss, length of hospital stay, operative time, percent change in eGFR, and complications were comparable between the groups. Conclusion: PCNL is a safe and effective treatment of kidney calculi in septuagenarians and older patients, even with the risk of higher comorbidities and poorer renal function than in younger patients.

Ultrasound Study

Objective: Urolithiasis of the transplanted kidney has an incidence of 0.2 to 1.7%, it increases the risk of infection in immunosuppressed patients and it can lead to ureteral obstruction that is often associated with deterioration of renal function. Urolithiasis of the transplanted kidney has different characteristics compared to the native kidney, due to the absence of innervation, which does not lead to colic pain. Percutaneous approach is an optimal choice in transplant patients. Material and methods: Here we report our experience in two cadaveric transplant patients with urolithiasis. The first case was a patient of 68 years with a 20 mm stone located in the transplanted kidney pelvis and another smaller in a lower calyx. The second case was a patient of 65 years with a 15 mm stone in the distal part of the transplanted ureter. In both cases the patients were asymptomatic, but they had a reduction in urine output associated with worsening of the transplanted kidney function. The diagnosis was performed in both cases with ultrasound study, showing a severe hydronephrosis and it was confirmed by computed tomography scan. In both cases, we performed a Percutaneous Nephrolithotomy (PCNL). Access was made after targeting the stone, through a lower pole puncture under ultrasound guidance. The first case was treated with pneumatic and laser energy, breaking stones through a nephroscope. In the second case we performed a laser lithotripsy of the ureteral stone, using a flexible videoureteroscope. At the end of both procedures a Double-J stent and a 14 Fr Malecot nephrostomy were positioned, that were removed at 6 weeks and 10 days, respectively. Results: Both patients achieved a resolution of the worsening of renal function, recovering the spontaneous diuresis. The surgical procedure using ultrasound guidance was safe and allowed quick access to the renal pelvis. Both patients experienced no bleeding or infection during hospitalization. Conclusions: Percutaneous Nephrolithotomy (PCNL) is an established safe and effective surgical treatment option for larger renal calculi in renal allografts. The ultrasound guided access to the transplanted kidney in percutaneous treatment of urolithiasis is useful and fast, minimizing patient exposure to ionizing radiation.

Objective This study aimed to present our experience of concomitant management of renal calculi and recurrent ureteropelvic junction obstruction (UPJO) with percutaneous nephrolithotomy (PCNL) and antegrade balloon dilation. Methods We retrospectively reviewed 31 patients who underwent PCNL and antegrade balloon dilation for treatment of renal calculi and recurrent UPJO. The inclusion criterion was the presence of UPJO after failed pyeloplasty with ipsilateral renal calculi. Success was defined as achievement of both symptomatic and radiographic resolution of any stones and obstruction. Results All operations were successful without grade III or higher postoperative complications. A stone-free status was observed in all patients and the overall success rate of the procedure was 87.1% (27/31). The success rate of the procedure was significantly higher in patients with mild or moderate preoperative hydronephrosis (96%) than in those with high-grade preoperative hydronephrosis (50%). Moreover, the success rate of the procedure was lower in patients with poor preoperative renal function (0%) than in those with good or moderate renal function (93.1%). Conclusion Combined PCNL and antegrade balloon dilation management represents a safe and effective approach for patients with renal calculi and recurrent UPJO after failed pyeloplasty.

Objective: To evaluate renal function change after percutaneous nephrolithotomy in patients with solitary kidney. Methods: A prospective study conducted in the urology department at Rizgary Teaching Hospital for a period of 15 months from first of June 2018 until the end of August 2019. It included nine adult patients, all of them with solitary kidney and undergone percutaneous nephrolithotomy for management of renal calculi. Patients were considered to have a solitary kidney in case of congenital abnormality, contralateral nephrectomy, or solitary functioning kidney with contralateral atrophy (relative function < 10%). All patients were received prophylactic antibiotics (Ceftriaxone) at induction of anesthesia. All percutaneous nephrolithotomy procedures performed under general anesthesia in the prone position. Serum creatinine and creatinine clearance before the operation, at day one and day 21 postoperatively, operation time, duration of hospitalization, and postoperative complications recorded. Results: In this study, Means of serum creatinine at 1 day and 21 days postoperatively were significantly decreased compared to preoperative s. creatinine level Mean of creatinine clearance significantly increased after 21 days postoperatively compared to preoperative test, while no significant change in creatinine clearance after one day postoperatively. Conclusion: Generally, percutaneous nephrolithotomy considered as a safe and effective option for treatment of renal stones in solitary kidney patients considering the overall rate of complications and minimal morbidity. Moreover, significant renal function improvement anticipated in the early postoperative period.

Uncommon Complication

Urinary lithiasis in transplanted kidney is a relatively uncommon complication. However, it may lead to a significant morbidity and loss of renal function. The report presents the case of a 32-year-old male renal-transplant recipient, with a stone in renal pelvis who was treated successfully by tubeless percutaneous nephrolithotomy (PCNL). The patient is currently stone free with no complication. This article also reviews in brief the treatment of this rare complication. Reviewing the literature showed that PCNL is safe and feasible procedure for treating nephrolithiasis in a transplanted kidney.
