BACKGROUND: Eosinophilic cystitis (EC) is a rare and specific transmural inflammatory disease in clinic. At present, its etiology is unknown, its clinical manifestations are diverse, and its auxiliary examination lacks specificity, so it is easy to be missed or misdiagnosed in clinical practice.
METHODS: A 72-year-old male patient with symptoms of lower urinary tract obstruction accompanied by hematuria was diagnosed with benign prostatic hyperplasia with bleeding by B-ultrasound and urinary CT examination. After being treated with catheterization, anti-infection and hemostasis, he was selectively treated with transurethral resection of prostate, but he saw a pattern mass on the right back wall of the bladder during the operation. Considering bladder tumor, he removed the lesion and gave pirarubicin for bladder perfusion. However, the postoperative pathological result was EC.
METHODS: The diagnosis of EC can only rely on pathological examination, and the accurate and positive rate of biopsy can be improved by obtaining muscle tissue as much as possible at the same time of multi-point biopsy.
METHODS: Prednisone and cetirizine were given orally after transurethral resection of lesions, and tamsulosin and finasteride were given regularly to treat benign prostatic hyperplasia.
RESULTS: No recurrence and abnormal urination were found during the follow-up for half a year, and the upper urinary tract function was normal.
CONCLUSIONS: The clinical manifestations of EC are atypical, the laboratory examination and imaging examination are not specific, and it is difficult to make a definite diagnosis before operation. The diagnosis depends on pathological examination. Transurethral resection of the lesion can obviously improve the positive rate of biopsy while completely removing the lesion, and the combined drug treatment can achieve satisfactory results in a short period of time. Active follow-up after operation is very important to identify the recurrence of the disease and prevent the upper urinary tract function from being damaged.

The use of ultrasound has been reported to be beneficial in challenging neuraxial procedures. The angled probe is responsible for the main limitations of previous ultrasound-assisted techniques. We developed a novel technique for challenging lumbar puncture, aiming to locate the needle entry point which allowed for a horizontal and perpendicular needle trajectory and thereby addressed the drawbacks of earlier ultrasound-assisted techniques.
Patient 1 was an adult patient with severe scoliosis who underwent a series of intrathecal injections of nusinersen. The preprocedural ultrasound scan revealed a cephalad probe\'s angulation (relative to the edge of the bed) in the paramedian sagittal oblique view, and then the probe was rotated 90° into a transverse plane and we noted that a rocking maneuver was required to obtain normalized views. Then the shoulders were moved forward to eliminate the need for cephalad angulation of the probe. The degree of rocking was translated to a lateral offset from the midline of the spine through an imaginary lumbar puncture\'s triangle model, and a needle entry point was marked. The spinal needle was advanced through this marking-point without craniocaudal and lateromedial angulation, and first-pass success was achieved in all eight lumbar punctures. Patient 2 was an elderly patient with ankylosing spondylitis who underwent spinal anesthesia for transurethral resection of the prostate. The patient was positioned anteriorly obliquely to create a vertebral rotation that eliminated medial angulation in the paramedian approach. The procedure succeeded on the first pass.
This ultrasound-assisted paramedian approach with a horizontal and perpendicular needle trajectory may be a promising technique that can help circumvent challenging anatomy. Larger case series and prospective studies are warranted to define its superiority to alternative approaches of lumbar puncture for patients with difficulties.

To describe the contemporary evolution of day-case bladder outflow obstruction (BOO) surgery in England and to profile day-case BOO surgery practices across England in terms of the types of operation performed and their safety profiles.
This was a retrospective observational analysis of Hospital Episode Statistics and UK Office for National Statistics data. All 111 043 recorded operations across 117 hospital trusts over 66 months, from 1 January 2017 to 30 June 2022, were obtained. Operations were identified as one of: transurethral resection of prostate (TURP); laser ablation or enucleation; vapour therapy; prostatic urethral lift (PUL); or bladder neck incision. Monthly day-case rate trends were plotted across the study period. Descriptive data, day-case rates and 30-day hospital readmissions were analysed for each operation type. Multilevel regression modelling with mixed effects was performed to determine whether day-case surgery was associated with higher 30-day hospital readmissions.
Day-case patients were younger, with fewer comorbidities. Time series analysis showed a linear day-case rate increase from 8.3% (January 2017) to 21.0% (June 2022). Day-case rates improved for 92/117 trusts in 2021/2022 compared with 2017. Three of the six trusts with the highest day-case rates performed predominantly day-case TURP, and the other three laser surgery. Nationally, PUL and vapour surgery had the highest day-case rates (80.9% and 38.1%). Most inpatient operations were TURP. Multilevel regression modelling found reduced odds of 30-day readmission after day-case BOO surgery (all operations pooled), no difference for day-case vs inpatient TURP, and reduced odds following day-case LASER operations.
The day-case rates for BOO surgery have linearly increased. Minimally invasive surgical technologies are commonly performed as day cases, whereas high day-case rates for TURP and for laser ablation operations are seen in a minority of hospitals. Day-case pathways to treat BOO can be safely developed irrespective of operative modality.

OBJECTIVE: Laser endoscopic enucleation of the prostate (EEP) for benign prostatic obstruction has become increasingly prevalent worldwide. Considering the medical cost-savings and concomitantly fewer nosocomial infections, the feasibility of same-day postoperative discharge of patients who have undergone laser EEP in terms of its safety and effectiveness has become a subject matter of growing interest. We aimed to review those studies focussing on day-case surgery (DCS) in patients undergoing laser EEP.
METHODS: A systematic search was conducted using PubMed-MEDLINE and Web of Science databases until October 2022 with the following search terms: \"same day discharge AND laser enucleation of the prostate\", \"day-case AND laser enucleation of the prostate\", \"same day surgery AND laser enucleation of the prostate\" and \"one day surgery AND laser enucleation of the prostate\" by combining PICO (population, intervention, comparison, outcome) terms. We identified 15 eligible studies.
RESULTS: While 14 of the studies focussed on holmium laser EEP, one focused on thulium laser vapoenucleation of the prostate. We observed an improvement in functional parameters in all studies we reviewed, and DCS success and readmission rates ranged between 35.3-100% and 0-17.8%, respectively. The complication rates varied between 0 and 36.7%, most of the complicatons were Clavien-Dindo (CD) I and II. CD ≥ III complications did not significantly differ between same day discharge (SDD) and non-SDD groups in the studies.
CONCLUSIONS: Laser EEP is feasible and promising DCS treatment option delivering improved functional parameters compared to baseline values, and lower perioperative complication and readmission rates in certain patients.

UNASSIGNED: Intraoperative hypothermia is a common but severe condition that is defined as a core body temperature below 36 °C. Accidental hypothermia can produce coagulopathy, immunosuppression and peripheral hypoperfusion that can ultimately lead to life-threatening ventricular arrhythmias and vital organ injury, and it is significantly associated with perioperative complications and mortality.
UNASSIGNED: We report the case of an 82-year-old man who presented with persistent ventricular tachycardia intraoperatively due to accidental hypothermia. The patient was diagnosed with benign prostatic hypertrophy and scheduled for transurethral resection of the prostate. Laboratory tests showed moderate anemia, and echocardiography indicated mild tricuspid and mitral regurgitation. The patient received general anesthesia with endotracheal intubation. Four hours after the start of surgery, the patient developed sudden ventricular tachycardia with severe hypotension. Arterial blood gas sampling indicated that there was no disturbance of electrolytes, acid-base balance or excessive bleeding. The rectal temperature was measured immediately, and the core temperature was 32 °C. The patient received antiarrhythmic therapy and rewarming measures. No additional ventricular arrhythmias appeared after the core temperature rose to 35 °C and the blood pressure returned to normal. The patient was transferred to the intensive care unit after surgery for further observation and was moved to the general ward the next day. He was discharged 4 days later without significant organ damage.
UNASSIGNED: Intraoperative hypothermia may increase ventricular arrhythmia risk, especially in elderly patients. Surgeons and anesthesiologists should pay more attention to preventing and reversing accidental hypothermia, necessitating aggressive efforts to maintain normothermia during surgery.

BACKGROUND: We determined and compared wait times for urological procedures at 2 centers in different health care systems to more fully understand the usefulness of wait times as a quality indicator.
METHODS: A retrospective review of patient wait times for transurethral bladder tumor resection was performed at Albany Medical Center, Albany, New York and Kingston General Hospital, Kingston, Ontario, Canada. The time from the decision for surgery until the completion of surgery (Wait 2) was determined for 495 consecutive patients during calendar years 2011 and 2012. Patient, surgeon and tumor factors that could potentially affect wait times were collected, as were wait times from referral to initial consultation (Wait 1) for new patients. These findings were contrasted with the wait times for 375 patients who underwent transurethral prostate resection.
RESULTS: Median Wait 2 time for transurethral bladder tumor resection was statistically but not clinically different at 24 days at Albany Medical Center and at 35 days at Kingston General Hospital. High grade and stage were associated with shorter wait times at Albany Medical Center but not at Kingston General Hospital. Median Wait 1 time was different at Albany Medical Center (13 days) vs Kingston General Hospital (25 days), significantly adding to the total wait. For transurethral prostate resection the Wait 2 times were more disparate at 29 and 58 days at Albany Medical Center and Kingston General Hospital, respectively.
CONCLUSIONS: The use of wait time as a measure of surgical quality of care is complex. These results suggest that measuring a summary wait time (Wait 2) may not identify the structural and process issues that affect care delivery.

BACKGROUND: Among prostate cancer, primary prostate squamous cell carcinoma (SCC) is a rare condition with low incidence, and secondary prostate SCC is rarer with fewer cases reported globally. This report presents an extremely rare case of secondary prostate SCC that metastasised from lung cancer.
METHODS: This study reports the case of a 77-year-old man who presented with acute urinary retention and dysuria and was admitted to our hospital. Physical and digital rectal examinations were conducted and revealed the overfilling of the suprapubic bladder and a slightly enlarged prostate without palpable nodules, respectively. The patient was tested negative for total and free prostate antigens (PSA) and had large masses in the upper lobes of both lungs and an irregularly enlarged prostate in the computed tomography images. The patient was inserted immediately with 18F triple-cavity Foley catheter to drain haematuria with blood clots. The patient was treated with electric coagulation haemostasis and transurethral resection of the prostate and subjected to postoperative histopathological analysis, which revealed the diagnosis of SCC. The patient was advised to undergo further radiation therapy and chemotherapy but rejected all follow-up treatments for lungs and prostate. The patient recovered uneventfully and was discharged 7 days after the operation. The patient remained alive after 6 months of follow-up.
CONCLUSIONS: Secondary prostate SCC is an extremely rare type of tumour. Surgical intervention plays a role in stopping bleeding and relieving urination problems, and timely treatment may led to favourable prognosis.

BACKGROUND: Anastomotic stenosis is a common complication of colorectal surgery with anastomosis. To explore a minimally invasive novel approach surgical method for the treatment of rectal anastomotic strictures using transurethral prostate resection instrumentation.
METHODS: From 2012 to 2022, 18 patients for the treatment of rectal anastomotic strictures using transurethral prostate resection instrumentation. The transurethral prostate resection instrumentation enters the rectum through the anus to incise the narrow anastomotic orifice in a 4-point radial manner under the resectoscope.
RESULTS: The surgery was successfully completed in 18 patients, and there were no postoperative complications. Postoperatively, 12 patients achieved satisfactory improvement in defecation after 1 incision, and 4 patients underwent another incision 3 months later. Two patients underwent incisions thrice, and the ease of defecation improved in a short period; however, they later underwent permanent colostomy due to repeated stenosis and pain.
CONCLUSIONS: The transanal 4-point radial incision of the prostate using transurethral prostate resection instrumentation is a minimally invasive, safe, effective, and simple surgical method for the treatment of rectal anastomotic stenosis supplemented by postoperative dilatation, and is worthy of clinical application.

BACKGROUND: Transperineal prostate biopsy is gradually becoming the standard methodology for diagnosing prostate cancer because of its high accuracy and low risk of infection, but careful preparation is not always highlighted before a transperineal biopsy. we reported two cases of hair embedding during transurethral resection of the prostate following transperineal puncture biopsy with a Bard MC1820 disposable biopsy needle. Histological examination did not find the hair follicle structure required for hair growth. The hair source was suspected to be percutaneously brought in by needle during the biopsya simulated experiment was used to analyze and reconstruct the process of hair embedding in prostate tissue.
CONCLUSIONS: Hair embedding caused by perineal prostate biopsy is a consumable-related adverse event, and skin preparation before a transperineal prostate biopsy is recommended.
