RESUMEN
BACKGROUND: Osgood-Schlatter disease (OSD) is a type of osteochondrosis and traction apophysitis that results from repeated contractions of the quadriceps femoris muscle on the tibial tuberosity. Its prevention, early diagnosis, and treatment are crucial because it causes chronic knee pain and surgical approaches are required if left untreated. Three-dimensional motion analysis is a useful approach for elucidating the pathological factors of OSD; however, it requires advanced cameras, sophisticated facilities, and expensive software. Conversely, the advent of technology has provided affordable video recording devices, and smartphone/tablet-based applications have enabled two-dimensional (2D) motion analysis. This emerging tool and artificial intelligence technology were used to analyze the pivot leg from videos recorded on a tablet device during the instep kicks of adolescent soccer players. Therefore, in this study, we aimed to determine whether the pathological factors for OSD occurring in the pivot foot can be identified through a simple 2D motion analysis using a tablet device. METHODS: In total, 94 knees of 47 soccer players (aged 14.1±0.8 years, all male) who belong to a single soccer club were evaluated. OSD was diagnosed using ultrasonography and physical examination (a positive bone fragment on ultrasonography or tenderness at the tibial tuberosity). Lower limb muscle tightness was evaluated using the finger-floor distance, straight leg raising test, heel-buttock distance, Thomas test, and ankle range of motion using a goniometer. We then performed motion analysis, and the instep kicking motion was recorded using a video camera on a tablet device. The joint angles of the hip, knee, and ankle were measured using a real-time human-pose detection system. Data were compared between the OSD and non-OSD groups. RESULTS: Overall, six of the 47 players (12.8%) were diagnosed with OSD. No correlation was found between lower limb tightness and the occurrence of OSD in all indices. However, the 2D motion analysis revealed that the knee flexion angle at the time of plantar placement during the instep kick movement was significantly larger in the OSD group than in the non-OSD group (OSD group: 42.0±7.2Ë, non-OSD group: 33.5±6.6Ë, *p=0.013). CONCLUSION: A video motion analysis revealed that the knee flexion angle during the instep kicking motion was significantly greater in athletes with OSD of the supporting foot.
RESUMEN
PURPOSE: To investigate the safety of transurethral ureteroscopy (URS) for urolithiasis in bedridden patients and to identify bedridden patient-specific risk factors for postoperative complications. METHODS: The patients who underwent URS for urolithiasis were divided into bedridden patients and good performance status (PS) patients, and the groups were compared regarding their clinical characteristics and postoperative complications. A multivariable logistic regression analysis was performed to evaluate independent predictors of postoperative febrile urinary tract infection (fUTI). RESULTS: A total of 1626 patients were included, 276 in the bedridden patient group, and 1350 in the good PS patient group. The bedridden patient group had a significantly higher age and higher proportion of females and had multiple comorbidities. In 77 patients (27.9%), 88 postoperative complications developed for the bedridden patient group. Clavien-Dindo grade III or IV complications were observed in only 8 patients. No grade V complications were observed. The most common complication was fUTI. The frequency of fUTI with grade III or IV for the bedridden patient group (2.2%) was higher compared with the good PS patient group (0.5%), but the difference was not statistically significant (p = 0.13). Bedridden patient-specific risk factors for fUTI included female sex, diabetes mellitus, cerebrovascular comorbidities, lower extremity contracture, and prolonged operative time. CONCLUSION: URS for urolithiasis is a feasible and acceptable procedure in bedridden patients, despite the moderate rate of postoperative complications. The identified risk factors provide a framework for risk stratification and individualized care in this unique patient population.

BACKGROUND: This study aimed to investigate factors, including the degree of hydronephrosis, that may be associated with decreased renal function after radical nephroureterectomy (RNU). METHODS: This study included 252 patients who underwent laparoscopic RNU with an estimated glomerular filtration rate (eGFR) ≥ 30 ml/min/1.73 m2 in three institutions. We assessed the association between hydronephrosis grade and perioperative renal function and performed a stepwise multivariate linear regression analysis to identify factors associated with postoperative eGFR. Patients with preoperative eGFR ≥ 50 ml/min/1.73 m2 were divided into a training set and an independent external validation set to develop a predictive model for postoperative renal function. RESULTS: The median preoperative and postoperative eGFR were 61.1 and 46.4 ml/min/1.73 m2, respectively. The eGFR preservation rates were 66.9%, 66.6%, 88.1%, and 100.0% in groups without, with mild, moderate, and severe hydronephrosis, respectively, and this difference was statistically significant (p < 0.001). Multivariate analysis revealed that factors predictive of postoperative eGFR included sex, preoperative eGFR, clinical T stage (cT3-4), and the presence of moderate or severe hydronephrosis. Our predictive model, based on these factors, positively correlated with actual postoperative renal function, and the similarity in categories with or without renal function insufficiency between predicted and actual postoperative renal functions was 78% in both training and validation sets. CONCLUSION: Moderate or severe hydronephrosis is associated with a modest postoperative decline in renal function, while mild hydronephrosis is not. Our predictive model may be useful in predicting postoperative renal function insufficiency and guiding decision-making for perioperative medical treatment.

In cases of rectal invasion by locally invasive prostate cancer (LAPC) leading to severe pain or bleeding, total pelvic exenteration (TPE) is necessary. Here, we present two cases of successful minimally invasive TPE: one performed laparoscopically for local recurrence with rectal bleeding after laparoscopic radical prostatectomy, and another done robotically for LAPC (clinical T4N1M0) accompanied by rectal bleeding. Medical treatments were ineffective in the latter case, and the tumor occupied a significant portion of the pelvis. We adopted a simultaneous transperineal approach and performed intracorporeal ileal conduit formation. Our cases highlight the challenging nature of minimally invasive TPE for symptomatic LAPC. Despite its complexity, these techniques prove viable and valuable in managing LAPC-related symptoms, emphasizing their practical utility in clinical settings.

Licorice can cause pseudoaldosteronism and QT prolongation as its side effect. Trigeminal nerve stimulation, including surgical intervention involving the face, can cause transient bradycardia, known as the trigeminocardiac reflex. Although rare, a combination of these two etiologies can cause ventricular tachycardia. A 50-year-old female patient with a history of hypertension and intake of an herbal drug containing licorice underwent impacted wisdom tooth extraction under general anesthesia. Immediately after placing a month-long prop for visualization in the oral cavity, sinus bradycardia occurred, followed by ventricular tachycardia and torsade de pointes. Mouth prop was removed and cardiopulmonary resuscitation was initiated, and the arrhythmia was resolved. Hypokalemia, metabolic alkalosis and normal aldosterone levels were observed. An inverted T wave and a prominent U-wave were observed on the electrocardiogram. Potassium excretion in urine was normal, although hypokalemia was present. The patient was treated with potassium correction.
RESUMEN
INTRODUCTION: Segmental ureterectomy (SU) has been proven effective in cases of distal upper tract urothelial carcinoma (UTUC). Nonetheless, SU has been performed infrequently in the real world, and there is no consensus on the preferred surgical technique in laparoscopic surgery. We describe our first experience of laparoscopic segmental ureterectomy (LSU) with psoas hitch ureteral reimplantation. MATERIALS AND SURGICAL TECHNIQUE: LSU starts using a fan-shaped, five-port, transperitoneal approach. First, the cancerous ureter segment is clipped to avoid tumor seeding, and then the diseased segment is dissected. Second, the psoas hitch is performed by fixing the external part of the ipsilateral dome of the bladder to the psoas muscle and its tendon. Third, at the top of the bladder, an incision is made in the muscle layer and mucosa. The ureter is then spatulated. A guide wire is used to place a retrograde ureteral double J stent. Finally, the anastomosis of the bladder and ureter mucosa is performed by interrupted suturing of both ends, followed by continuous suturing, and the muscular layer of the bladder is closed in a double layer. We performed LSU for distal UTUC in 10 patients. There was no decrease in renal function before or after surgery. During follow-up, three patients experienced a recurrence of urothelial carcinoma in the bladder and one patient had a local recurrence. DISCUSSION: LSU is a safe and feasible procedure in our experience, and it can be recommended for selected cases of distal UTUC with optimal perioperative, renal functional, and oncologic outcomes.

INTRODUCTION: This study aimed to identify preoperative risk factors and create a risk classification for intravesical recurrence of upper urinary tract urothelial carcinoma only after laparoscopic radical nephroureterectomy in a multi-institutional cohort. METHODS: We retrospectively analyzed 283 patients who had undergone laparoscopic radical nephroureterectomy for nonmetastatic upper tract urothelial cancer between March 2002 and March 2020. The cumulative incidence of intravesical recurrence for 224 patients without previous or concomitant bladder cancer was examined using multivariate Fine-Gray competing risks proportional hazards models. A risk stratification model was created to predict subsequent patient outcomes based on the results. RESULTS: The median follow-up duration was 33.3 months, and 71 (31.7%) patients experienced intravesical recurrence. The estimated cumulative incidence of intravesical recurrence at one and 5 years was 23.5% and 36.4%, respectively. In multivariate analysis, the presence of ureter tumors and multiple tumors were shown to be independently significant predictive factors for intravesical recurrence. Based on the results, we classified patients into three risk groups. The cumulative incidence rates of intravesical recurrence within 5 years after surgery were 24.4%, 42.5%, and 66.7% in the low-, intermediate-, and high-risk groups, respectively. CONCLUSIONS: We identified risk factors and created a risk classification model for intravesical recurrence of upper urinary tract urothelial carcinoma only after laparoscopic radical nephroureterectomy. Based on this model, an individualized surveillance protocol or adjuvant therapy could be provided.

Objectives: To investigate the recurrence patterns and the atypical oncologic failure (AOF) defined as the presence of atypical recurrences, such as retroperitoneal carcinomatosis or port-site recurrence, after laparoscopic radical nephroureterectomy (LRNU). Methods: LRNU performed at three institutions were included in this retrospective study. The primary endpoints were the first recurrence site and recurrence-free survival. The recurrence sites were classified as atypical recurrences, such as retroperitoneal carcinomatosis or port-site recurrence, as well as distant, local, and intravesical. The Kaplan-Meier curves were obtained to elucidate the time until recurrence and survival. Results: A total of 283 patients were included in the final analysis. Postoperative pathology was T3 or higher in 112 (40%) patients. The median follow-up period was 31 months, and the 3-year recurrence-free, cancer-specific, and overall survival rates were 69.6%, 78.1%, and 72.0%, respectively. The first recurrence sites involved distant, local, atypical, and intravesical recurrences in 51 (18%), 36 (13%), 14 (5%), and 94 (33%) patients, respectively. Of the 14 patients with AOF, 12 had pathologically locally advanced tumors, but seven patients had a preoperative diagnosis of clinical stage T2 or less. Conclusion: A small number of AOF cases were found after LRNU for patients with upper tract urothelial carcinoma. Careful patient selection is critical for AOF prevention.

PURPOSE: Ultrasonography and computed tomography urography are two commonly used modalities to image the upper tracts for the evaluation of hematuria. This study evaluated the efficacy of ultrasonography for the detection of upper tract urothelial carcinoma compared to computed tomography urography as a standard reference. METHODS: This retrospective study included patients with urothelial carcinoma of the renal pelvis and/or ureter who were diagnosed using computed tomography urography and underwent surgical treatment. We calculated the sensitivity of ultrasonography in upper tract urothelial carcinoma diagnosis, further classified the degree of hydronephrosis on ultrasonography, and analyzed the relationship between the sensitivity and the degree of hydronephrosis and tumor location. Additionally, the usefulness of the combination of the screening ultrasonography findings, the presence of gross hematuria, and/or urine cytology was analyzed. RESULTS: This study included 136 patients with upper urothelial carcinoma. Ultrasonography in the diagnosis had 45.6% sensitivity, and ultrasonography findings, including the detection of hydronephrosis, were present in 72.8%. The presence of hydronephrosis and tumor location were associated with detection by ultrasonography. The tumor was identified in a total of 134 (98.5%) patients by combining tumor detection and hydronephrosis using ultrasonography with gross hematuria and positive urine cytology as screening. CONCLUSION: Ultrasonography showed acceptable sensitivity for upper tract urothelial carcinoma diagnosis. Considering the hydronephrosis findings, ultrasonography is a useful screening tool for upper tract urothelial carcinoma. Additionally, excessive computed tomography examinations can be reduced by adding gross hematuria and positive urine cytology.

OBJECTIVE: To examine the safety and efficacy of ureteroscopy (URS) for urolithiasis in octogenarians, and identify preoperative risk factors for the incidence of postoperative complications. METHODS: The patients who underwent URS for urolithiasis were divided into octogenarians and younger patients (age: <80 years), and the groups were compared regarding their clinical characteristics, intraoperative and postoperative complications, and stone-free rate. The predictors of postoperative complications were evaluated using logistic regression models. RESULTS: A total of 1207 patients were included, 166 in the octogenarian patient group and 1041 in the younger patient group. The proportion of female patients (p < 0.001), American Society of Anesthesiologists (ASA) score (p < 0.001), rate of preoperative pyelonephritis (p < 0.001), and diabetes mellitus (p = 0.003) were higher in the octogenarian group. No statistically significant differences were found between the two groups regarding stone size, location, and intraoperative complications. Postoperative complications, which reached a significant difference, were observed in 34 (20.5%) octogenarians and 117 (11.2%) younger patients (p = 0.002). However, age itself was not significantly associated with postoperative fever, the most frequent postoperative complication, in multivariate analysis. Female sex, ASA score of ≥3, history of diabetes mellitus, and prolonged operative time (≥120 min) were the significant predictors of fever. The stone-free rate in the octogenarian group was superior to that in the younger patient group (80.1% vs. 70.6%, respectively; p = 0.035). CONCLUSION: Our results suggest that URS for urolithiasis can be safely and effectively applied to octogenarians in selected cases.

OBJECTIVES: To identify risk factors for infectious complication of ureteroscopy after obstructive acute pyelonephritis (OAPN). PATIENTS AND METHODS: This single-center, retrospective cohort study (#20200002, retrospectively registered in February 1st, 2020) included patients who underwent emergency drainage for OAPN and subsequently underwent ureteroscopic stone removal between January 2006 and December 2020. Multivariable analysis was conducted using demographic and stone-related factors to determine those that could predict postoperative febrile urinary tract infection (UTI). RESULTS: Overall, 432 patients underwent ureteroscopy after OAPN. The stone-free rate was 84.3%, whereas the overall and major complication rates were 17.6% and 3.2%, respectively. A total of 70 (16.2%) patient developed febrile UTI, among whom 34 (7.9%) and 11 (2.5%) developed sepsis and severe sepsis, respectively. Multivariable analysis identified diabetes mellitus [odds ratio (OR) 1.98, 95% confidence interval (CI) 1.05-3.74], duration from drainage to surgery >1 month (OR 2.28, 95% CI 1.20-4.74), and simultaneous retrograde intrarenal surgery (OR 2.96, 95% CI 1.35-6.48) as significant risk factors for UTI. After dividing patients into low- (0), intermediate- (1), and high- (2-3) risk groups according to the number of factors they had, the risk of postoperative UTI was 6.3%, 14.5%, and 27.7%, respectively (p for trend <0.001). CONCLUSIONS: Patients who underwent ureteroscopy after OAPN were at risk for postoperative UTI, despite its efficacy. Simultaneous retrograde intrarenal surgery should be carefully planned, especially for patients with diabetes mellitus or extended surgery wait times.

BACKGROUND: This study aimed to compare the incidence of postoperative complications occurring within 30 days of surgery between octogenarians and younger patients and identify preoperative risk factors for the incidence of postoperative complications. Moreover, we also compared the oncological outcomes between octogenarians and younger patients. METHODS: This retrospective study included 283 patients who underwent laparoscopic radical nephroureterectomy for upper tract urothelial carcinoma from 2002 to 2020. The patients were divided into octogenarians and younger patients (age: < 80 years), and their clinical characteristics, perioperative parameters, and postoperative complications were evaluated. The predictors of postoperative complications were evaluated using logistic regression models. Recurrence-free survival, cancer-specific survival, and overall survival were measured using the Kaplan-Meier method. RESULTS: Twelve (17.1%) octogenarians and 40 (18.7%) younger patients had postoperative complications. No significant difference in the incidence of postoperative complications was observed between octogenarians and younger patients (p = 0.14). A high body mass index was a significant risk factor for complications (p = 0.03). The 5-year recurrence-free survival, cancer-specific survival, and overall survival rates for octogenarians and younger patients were 72% and 64% (p = 0.31), 76% and 63% (p = 0.63), and 43% and 63% (p = 0.06), respectively. CONCLUSION: Laparoscopic radical nephroureterectomy can be performed in octogenarians with complication rates similar to those in younger patients. Similarly, the outcomes of laparoscopic radical nephroureterectomy for oncological control do not differ significantly between octogenarians and younger patients. This procedure is safe and effective for selected octogenarians.

Synovial hemangioma, a rare benign tumor that occurs most frequently in the knee in children and young adults, has four histological subtypes: Venous, arteriovenous, cavernous and capillary hemangiomas. Since the clinical presentation and radiological findings of synovial hemangioma are non-specific, there is frequently a long period between the onset and the diagnosis. The cases of nine patients, pathologically diagnosed with synovial hemangioma and surgically treated, were retrospectively analyzed. All nine patients had persistent knee pain. In addition, three patients also had a swollen knee with intra-articular hemorrhage. Plain radiography revealed intra-articular phleboliths in two patients. In seven patients, T1-weighted magnetic resonance imaging showed low signal intensity with small signal voids. On T2-weighted imaging, all patients showed high signal intensity containing small signal voids. All patients underwent surgical excision; there was no postoperative recurrence after the final operation, and the knee pain had disappeared at the final follow-up. From the pathological findings, the diagnoses were venous hemangioma, cavernous hemangioma and capillary hemangioma (three patients each).
RESUMEN
To elucidate and compare the efficacy and safety of the reduced (30 shocks/min with 1200 shocks/session) and standard protocols (60 shocks/min with 2400 shocks/session) of extracorporeal shockwave lithotripsy (SWL) for ureteral stones treatment. This study was a retrospective review of 2410 SWL procedures with reduced or standard protocols (groups R and S) in 1106 patients for ureteral stones between March 2014 and March 2021. The primary outcome was treatment success, defined as the absence of residual fragments on ultrasonography and plain radiography within 30 and 90 days. A multivariate logistic regression and propensity score matching analysis evaluated the association between the reduced protocol and treatment success. This study included 311 and 544 patients in the reduced (R) and standard (S) protocol groups, respectively. The patient's characteristics were comparable, excluding the lithotripter machine. No significant difference was observed between groups R and S in treatment success rates within 30 (63.3 vs. 65.8%, p = 0.50) and 90 days (88.7 vs. 91.5%, p = 0.18). The multivariate analysis indicated no significant association between reduced protocol and treatment success within 30 and 90 days (p = 0.44 and p = 0.68, respectively). Propensity score matching showed no significant difference in the treatment success rates within 30 and 90 days. The Extremely slow, half number protocol outcomes are comparable to those of the standard protocol for treating ureteral stones.

BACKGROUND: Recent progress in the chemotherapy and surgical procedures for osteosarcoma have enabled the preservation of limb function even when cancer occurs in the distal radius, a rare primary site of osteosarcoma. CASE REPORT: We describe a case of osteosarcoma that occurred in an 18-year-old, male Kyudo (Japanese archery) archer's left distal radius. Since the patient desired to resume Kyudo and the left hand was quite important for gripping a bow, we chose partial wrist arthrodesis (fibulo-scapho-lunate arthrodesis) with free vascularized fibular grafting (FVFG) as the reconstruction procedure following wide resection. After the wide resection, the major axis of bone defect was 8 cm. We harvested a free vascularized fibular graft with fascio-cutaneous flap with wide fascia to reconstruct the gliding surface of the extensor tendon. Fibula-proximal radius and fibulo-scapho-lunate fixation was performed by locking plates individually. Vascular anastomosis was performed between the radial artery and peroneal artery in a flow-through manner. Two peroneal veins were anastomosed with the radial vein and cephalic vein. CONCLUSION: Fibulo-scapho-lunate arthrodesis with FVFG may provide satisfied stability and function even in a Kyudo archer. The patient obtained sufficient wrist stability and grip strength, and could resume Kyudo.
RESUMEN
Recently, ureteroscopic lithotripsy remains the standard treatment for urolithiasis, with postoperative febrile upper urinary tract infection (fUTI) being one of its most significant complications. The current study sought to investigate the treatment outcomes of ureterorenoscopy (URS), morbidity and risk factors of postoperative fUTI at our hospital. A total of 1,235 patients who underwent URS (including those who underwent only semi-rigid URS) for upper urinary tract stones at our hospital between October 2011 and December 2019 were retrospectively analyzed. Patients had a median age of 63 years and a median stone length of 11.4 mm. F-URS was performed in 1,188 cases (96.2%) among whom 92.1% were stone-free or had stones that fractured into dust. Postoperative fUTI and sepsis occurred in 127 (10.3%) and 18 (1.5%) patients, respectively. Multivariate analysis identified female sex, American Society of Anesthesiologists (ASA) score ≥ 3, calculus length ≥ 20 mm, history of diabetes mellitus, and history of obstructive pyelonephritis as risk factors for postoperative fUTI. The scoring system (range 0-4) were positively correlated with the postoperative fUTI rate (score 0 : 3.1%, 1 : 12.4%, 2 : 14.1%, 3 : 23.7%, 4 : 40%). A significant difference in the rates was noted between those with a score of 0 (low-risk group), 1-2 (intermediate-risk group), and 3-4 scores (high-risk group). In conclusion, the overall incidence of postoperative fUTI was 10.3%, which was associated with sex, poor ASA scores, stone size, presence of diabetes mellitus, and history of pyelonephritis. The scoring system created using these factors can be useful in predicting postoperative fUTI.

We created an indoor forest bathing environment in a sunlight-type environmentally controlled chamber and both physiological and psychological measurements were conducted for the evaluation of mental fatigue reduction. At first, a working memory load experiment was performed among 10 participants in a space without plants to identify an indicator correlating with feelings of fatigue, using the cerebral activity of the prefrontal cortex. Then, the indicator was used to evaluate whether a 20-min exposure to an indoor forest bathing environment reduced the level of the feeling of fatigue. The working memory load experiment demonstrated that, when mental fatigue increased, the amount of oxygenated hemoglobin (oxy-Hb) in the right prefrontal cortex and the right-left difference in oxy-Hb (ΔRL oxy-Hb) in the prefrontal cortex increased. These were proposed as indicators of mental fatigue. In the indoor forest bathing experiment, staying in an indoor green space showed that the subjective values of feeling of fatigue decreased and ΔRL oxy-Hb decreased. Since these results demonstrated an opposite effect to the increase in ΔRL oxy-Hb related to the feeling of fatigue, it was inferred that the decrease in ΔRL oxy-Hb reflected the fatigue reduction in the indoor forest bathing environment.

Objectives: The aim of this study was to investigate the oncological outcomes and recurrence patterns in clinically node-negative patients with renal pelvic and/or upper or middle ureteral tumors after template-based retroperitoneal lymph node dissection (RPLND) in conjunction with retroperitoneal laparoscopic radical nephroureterectomy (LRNU). Materials and Methods: A total of 283 patients who received LRNU with and without RPLND at three Japanese institutions were enrolled. The template for RPLND included the renal hilar and para-aortic lymph nodes (LNs) (left side) and renal hilar, paracaval, retrocaval, and intra-aortocaval LNs (right side). The LNs and kidneys were removed en bloc. The primary endpoint was set as recurrence-free survival. All RPLND cases were matched one-to-one with no-RPLND cases using a propensity score matching approach, and 47 matched pairs were included in analyses. Results: Compared with the control group, significant differences were not observed in the RPLND group in terms of operation time, blood loss, postoperative complication rate, and pathological findings. The estimated 5-year recurrence-free survival was significantly higher in the RPLND group (86.8%) compared with the group without RPLND (64.2%) (p = 0.014). The estimated 5-year cancer-specific survival showed a similar tendency; however, it did not reach a statistically significant difference (87.5% vs 71.3%, respectively; p = 0.168). As for the first recurrence site, the RPLND group showed a lower incidence of distant recurrence, while no significant difference was observed in the rate of regional LN recurrence. Conclusions: This study suggests that template-based RPLND in conjunction with retroperitoneal LRNU efficiently improves recurrence-free survival by reducing distant recurrences.

Subcapsular renal hematoma is a complication of extracorporeal shock wave lithotripsy or percutaneous nephrolithotripsy. Although it can occur after transurethral ureterolithotripsy (TUL), there is no consensus on the risk factors, outcomes, and its management. This study aimed to elucidate the clinical courses of patients with subcapsular hematoma after TUL. We retrospectively investigated 1,235 patients who underwent TUL from October 2011 to December 2020 at our hospital and identified cases with subcapsular hematoma diagnosed after surgery. Subcapsular hematoma was diagnosed in 5 of the 1,235 (0.40%) patients, whose median age was 63 (49-69) years. The median operation time, hematoma diameter, and hemoglobin decrease were 66 (35-115) min, 8.2 (5.4-10.5) cm, and 1.6 (0.7-2.6) g/dl, respectively. All patients were conservatively managed without invasive interventions (eg, embolization), although one patient required blood transfusion. In conclusion, this study presented five cases with renal subcapsular hematoma after TUL that could be conservatively managed. It is important not to miss the timing of therapeutic intervention while observing the progress after diagnosis.
