Abstract
Urolithiasis, or the formation of calculi in the urinary system, represents a prevalent urological condition frequently encountered among individuals aged 30 to 55 years. An in-depth analysis of the composition of these calculi holds significant promise in shedding light on the underlying etiological and pathogenic factors contributing to this ailment. The primary objective of this study was to delineate the principal components comprising urinary system calculi within a cohort of patients who sought medical intervention at a tertiary grade A hospital located in Baoding City. Furthermore, our investigation entailed a comprehensive examination of the physical and morphological characteristics exhibited by these calculi. In this study, a total of 2307 individuals afflicted with urinary system calculi were recruited as participants, and a corresponding number of 2307 calculous specimens were subjected to thorough examination. The specimens were examined using infrared spectroscopy. We collected and examined patient data including gender, age, location of the calculi, employment status, residential area, and other factors. The middle-aged demographic exhibited a conspicuous predilection for urinary system calculi, wherein a notable gender disparity was observed, with a male-to-female ratio of 1.63 to 1. Among the enrolled patients, kidney calculi were prevalent in 1270 cases, ureteral calculi were documented in 983 cases, and bladder calculi were encountered in 46 instances. Notably, the principal components comprising these calculi were identified as calcium oxalate and apatite, while uric acid and ammonium magnesium phosphate were comparatively less frequently encountered. Furthermore, the analysis of calculus composition across patients residing in distinct geographical regions did not reveal any statistically significant variations. The identification of components within upper urinary tract calculi plays a pivotal role in elucidating the root causes of calculus formation. This valuable information empowers healthcare professionals, particularly nursing staff, to provide personalized dietary and health guidance to patients, thereby enhancing the quality of care and promoting more effective management of this condition.

BMC Urol 2023; 23:197. [PMID: 38031043 PMCID: PMC10687924 DOI: 10.1186/s12894-023-01368-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Accepted: 11/13/2023] [Indexed: 12/01/2023] Open
Abstract
BACKGROUND Although PCNL has been used for a long time to treat nephrolithiasis, there is still contradictory information concerning the use of the dilation method. In this study, we aimed to compare conventional sequential Amplatz dilatation (SAD) using ten dilators and a method using three dilators (12, 20, and 30 Fr), which we named "three-shot dilatation" (3SD), in terms of fluoroscopy time (FT), operation time, bleeding and stone-free rates. METHODS The study included patients who underwent PCNL with the SAD and 3SD methods. A different surgeon with extensive endourology experience applied each technique. One of the surgeons operated on the patients using the SAD method with ten dilators, and the other surgeon performed the operations using the 3SD method involving three Amplatz dilators (12, 20, and 30 Fr). RESULTS A total of 283 patients, 138 in the 3SD group and 145 in the SAD group, were included in the study. The mean age of the patients was 47.32 ± 13.71 years. There was no statistically significant difference between the two groups regarding preoperative characteristics (p > 0.05). The FTs of access 2, total access, and total operation were significantly shorter in the 3SD group (p = 0.0001). The decrease in hemoglobin was statistically significant in the 3SD group compared to the SAD group (p = 0.022), while the blood transfusion requirements of the groups were similar (p = 0.176). There was no statistically significant difference between the two groups regarding stone-free rates (p = 0.973). In four patients in the SAD group, re-access was necessary due to the loss of passage due to the guide wire slipping out of its place. CONCLUSION Intraoperative FT can be shortened using the described 3SD method without compromising surgical safety. However, this method can be used as an intermediate step in the transition to one-shot dilation by surgeons experienced in performing SAD.

Abstract
This study evaluated the clinical value of color Doppler ultrasound-guided percutaneous nephrolithotomy (PCNL) in avoiding bleeding caused by punctured blood vessels. Herein, we retrospectively included patients who underwent color Doppler ultrasound-guided PCNL or PCNL using the conventional channel technique from August 2018 to August 2022. The clinical characteristics of patients during surgery, complications, and hospital stay were recorded and compared. Overall, 228 patients were enrolled, with 126 patients (age, 47.6 ± 13.2 years; men: 57.14%) in the color Doppler ultrasound-guided PCNL group and 102 patients (age, 46.6 ± 12.3 years) in the B-mode ultrasound-guided puncture group. The total operation time (63.5 ± 15.5 vs. 61.3 ± 16.3 min, p = .5236) and stone clearance rate (86.50% vs. 83.33%, p = .7139) were similar between the two groups. However, the puncture time for the color Doppler ultrasound-guided PCNL group was longer than that for the B-mode ultrasound-guided puncture group (5.1 ± 2.3 vs. 2.6 ± 1.6 min, p = .0019). Moreover, the length of postoperative hospital stay in the color Doppler ultrasound-guided PCNL group reduced significantly by ∼1 day compared with that in the B-mode ultrasound-guided puncture group (4.5 ± 1.6 vs. 5.6 ± 2.1 days, p = .0087). The blood transfusion rate (1.58% vs. 4.9%, p = .0399), sedation-related adverse event rate (0.79% vs. 2.9%, p = .0332), perineal hematoma incidence (0% vs. 2.94%, p < .0001), and serum decreased hemoglobin levels (12.2 ± 9.7 vs. 23.5 ± 10.1 g/L, p < .001) after color Doppler ultrasound-guided PCNL were significantly lower than those after B-mode ultrasound-guided puncture. The stone clearance rate was similar between the two groups, with a similar operation time. Moreover, color Doppler ultrasound-guided PCNL shortened the postoperative hospital stay and decreased Hb levels, blood transfusion rate, and perineal hematoma incidence.

Abstract
Introduction: Three-dimensional (3D) reconstruction is a novel imaging technique widely used to improve surgical operations. Some studies have identified its role in Urology for percutaneous nephrolithotomy (PCNL). Objective: To explore the potential benefits of 3D reconstruction technology in PCNL for complex renal calculi treatment. Methods: A retrospective study involving 139 patients with complex kidney stones who underwent PCNL was conducted between September 30, 2018, to September 30, 2019. Group A patients (72) underwent the 3D reconstruction technique before PCNL, while group B (67) did not. The operation time, the duration of the hospital stay, the puncture accuracy, the decrease in hemoglobin concentration, the stone clearance rate, and the postoperative complications were noted and compared between the two groups. Results: The initial stone clearance rates 2 weeks after PCNL were 81.9 and 64.2% in groups A and B, respectively (P < 0.05). The first-time puncture success rates were 87.5 and 47.8 % in groups A and B, respectively (P < 0.05). Group A had a shorter operation time than group B (62 vs. 79 min, P < 0.05). Besides, the 3D reconstructive technique-assisted patients (91.7%) had no or mild complications, compared with (74.6%) group B patients. There was no significant difference in hemoglobin decline and hospital stay between the two groups. Conclusions: The 3D reconstruction technology is an effective adjunct to PCNL in the complex renal calculi treatment.

Abstract
OBJECTIVES This study aimed to describe a novel double-sheath vacuum suction minimally invasive percutaneous nephrolithotomy (mini-PCNL) to overcome the deficiencies of the conventional procedure. PATIENTS AND METHODS Between March 2019 and December 2019, 65 patients (37 males and 28 females) with a mean age of 41 years (range 23-69) underwent mini-PCNL with double-sheath vacuum suction. It consisted of an F20 Y-shaped sheath as an outer sheath and an F16 Y-shaped sheath as an inner sheath, in which the inner sheath was longer than the outer sheath. The oblique arm of the outer sheath and the inner sheath was connected to the perfusion inflow and the vacuum suction, respectively. A 550-μm holmium-YAG laser was introduced for stone fragmentation through the working channel of the mini-nephroscope, which was no longer connected to the perfusion fluid. RESULTS All procedures were successful. Mean operation time was 50.2 min (range 39-83). Mean hemoglobin decrease was 5.2 g/L (range 1.0-15.5), and no patient needed a blood transfusion. One patient (1.5%) with low fever (<38°C) at day 1 had returned to normal at day 2 without administration of antibiotics. There were no Clavien grade 2-4 complications. Mean postoperative hospital stay was 2.4 days (range 2-6). The initial stone-free rate of PCNL was 81.53% (53 of 65 patients). One month after surgery, the final stone-free rate increased to 90.77% (59/65 patients). CONCLUSIONS The double-sheath vacuum suction mini-PCNL is a safe and effective modality for large renal stones, which might increase the efficiency of stone extraction with low intrapelvic pressure.

The learning curve for access creation in solo ultrasonography-guided percutaneous nephrolithotomy and the associated skills. Int Urol Nephrol 2016; 49:419-424. [PMID: 28035623 DOI: 10.1007/s11255-016-1492-8] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2016] [Accepted: 12/20/2016] [Indexed: 12/17/2022]
Abstract
AIM The aim of the current trial was to evaluate the learning curve of access creation through solo ultrasonography (US)-guided percutaneous nephrolithotomy (PCNL), and clarify the technical details of the procedure. MATERIALS AND METHODS We evaluated the first 240 solo US-guided PCNLs performed by one surgeon at our institution. The data including the puncture procedure, access characteristics, access-related complications and stone-free rates were assessed in four sequential groups. RESULTS The puncture duration and number of times decreased from a mean of 4.4 min and 2.1 times for the first 60 patients to 1.3 min and 1.2 times for the last 60 patients. There was a significant decrease from 3.7 min and 1.8 times for the 61th-120th patients to 1.5 min and 1.3 times for the 121th-180th patients. All of the access-related severe bleeding appeared in the first 120 patients, while perforations only occurred in the first 60 patients. The stone-free rates were 68.3, 83.3, 90.0, and 93.3% for the four sequential groups. CONCLUSION The increase in experience lead to an improvement in the puncture duration and times, which accompany with better stone-free rates and lower complications. We propose that 60 operations are sufficient to gain competency, and a cutoff point of 120 operations will allow the surgeon to achieve excellence in the solo US-guided PCNL.

Abstract
OBJECTIVE To evaluate the efficacy and safety of wideband Doppler ultrasound-guided mini-endoscopic combined intrarenal surgery (mini-ECIRS) for large renal stones. MATERIALS AND METHODS This study included 41 patients with large renal stones (>30 mm) treated by mini-ECIRS using a retrograde flexible ureteroscope and miniature nephroscope by wideband Doppler ultrasound guidance in the modified Valdivia position from January 2013 to September 2015. Surgical parameters, including the stone-free rate, operative time, complications (especially hemorrhagic complications), and hemoglobin drop were recorded and analyzed. Univariate analysis was performed to identify risk factors for a hemoglobin drop of ≥1 g/dL. RESULTS The mean stone size, including staghorn calculi in 41.4% of cases, was 45.5 ± 14.7 mm. Percutaneous access into the calices using wideband Doppler ultrasound was successful in all cases. The mean total operative time was 158.4 ± 51.3 minutes. The mean mini-ECIRS time (from first percutaneous puncture to end of procedure) was 106.2 ± 36.0 minutes. The initial stone-free rate was 73.2% (n = 30). The final stone-free rate after auxiliary treatment was 97.5% (n = 40). The mean hemoglobin drop was 0.54 ± 0.65 g/dL. Three (7.3%) postoperative modified Clavien grade II complications occurred. Univariate analysis revealed no significant risk factors for a hemoglobin drop of ≥1 g/dL. CONCLUSION Wideband Doppler ultrasound-guided renal puncture is safe and feasible. Wideband Doppler ultrasound-guided mini-ECIRS is a beneficial, versatile, and safe treatment option for management of large renal stones of >30 mm.

Abstract
OBJECTIVES To assess the safety and efficacy of combining Doppler ultrasound with X-ray-guided percutaneous nephrolithotomy (PCNL) with one-step balloon dilation for management of complex renal stones. MATERIAL AND METHODS We retrospectively analyzed 85 renal stone patients who underwent 89 PCNLs from January 2011 to May 2012. Doppler ultrasound with X-ray-guided PCNL with one-step balloon dilation was finished on the Fluoroscopic Table (Siemens, Berlin, Germany) with the patient under general anesthesia. RESULTS The study included 85 patients (49 male and 36 female) with a mean age of 42.5 ± 16.4 years. All patients underwent 89 PCNLs (4 patients had bilateral stones). The mean operative time was 72.8 min (range: 35-140). The average fluoroscopic screening time was 5.55 ± 1.81 s (range: 4-12). Successful access to the collecting system was 98.9% (88/89). Although most of the cases (85/89) were managed satisfactorily by a single tract, a second tract was used in 4 cases. No severe complications occurred. The stone-free rate of PCNL monotherapy was 77.5% (69/89). At 3 months, the stone-free rate increased to 89.9% (80/89) after shock wave lithotripsy. CONCLUSIONS PCNL with one-step balloon dilation for the management of complex renal stones under the guidance of combining Doppler ultrasound with X-ray is safe and effective because of its high stone-free rate and low operative time.

Abstract
OBJECTIVE To evaluate the intraoperative outcomes of percutaneous renal access using fluoroscopic-guided access (FGA) vs endoscopic-guided access (EGA). METHODS A retrospective record review was conducted of patients undergoing percutaneous nephrolithotomy (PCNL), categorized by the method of achieving renal access. Patients were randomly assigned to 1 of 2 endourologists: 1 practicing EGA and the other practicing FGA. Patient demographics, baseline characteristics, and operative and postoperative outcomes were compared using univariate and multivariate analysis. RESULTS From August 2010 to January 2012, 159 patients underwent PCNL (40% EGA, 60% FGA). No significant difference was observed between groups in age (P = .06), American Society of Anesthesiologists Physical Status Classification (P = .7), number of stones (P = .058), cumulative stone diameter (P = .051), number of calyces involved (P = .82), and stone density (P = .49). Body mass index (BMI) was higher in patients undergoing EGA (P = .013). Patients undergoing EGA had shorter fluoroscopy time (3.2 vs 16.8 minutes, P <.001) and lower access number (1.03 vs 1.22 P = .002). Fluoroscopy time was longer for FGA than for EGA after adjusting for BMI, staghorn stones, and access number (P <.001). No significant difference was noted in change in hemoglobin, blood transfusion rate, operative time, or intraoperative complications between groups. Procedures were aborted due to bleeding more commonly in the FGA (8%) than in the EGA group (0%, P = .02) A secondary procedure for stone management was required in 2 (3.2%) of the EGA group compared with 12 (12.5%) of the FGA group. CONCLUSION EGA is safe and effective and leads to decreased fluoroscopy time, decreased need for multiple accesses, and decreased risk of early termination of the procedure or need for secondary procedures.
