Nephron sparing surgery (NSS) is of proven benefit among those with small renal masses. Hilar tumours are usually offered radical surgery due to the presumed difficulty in dissection, upgrading to tumour stage, and risk of conversion to radical surgery. We present our results of patients with hilar tumour undergoing nephron sparing surgery. We performed a retrospective analysis of patients who underwent NSS for renal hilar tumours in our tertiary referral institute from June 2017 to December 2022. The case sheets of all the patients who had undergone NSS were analysed and their radiology images reviewed. Those with hilar tumours were analysed based on demographic characters, perioperative and postoperative and follow-up details. Among a total of 21 patients undergoing partial nephrectomy, ten had hilar tumours. The median age was 43 years. Nine patients had robot-assisted partial nephrectomy and one underwent open partial nephrectomy. Seven patients had incidentally detected tumours. One had Grade 3 chronic kidney disease. The mean operative time and robot console time were 225 and 125 min, respectively. Median warm ischaemia time (WIT) was 36 min (25–48 min). One patient had grade 2 complication and two had grade 3 complication. Eight had clear cell renal cell carcinoma and one had positive margin. None had recurrence at a median follow-up of 38 months. Nephron sparing surgery, especially with robot-assisted approach, is feasible in hilar tumours with prognosis and complications similar to non-hilar tumours in short-term follow-up.","PeriodicalId":7432,"journal":{"name":"African Journal of Urology","volume":"203 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139517904","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ESWL as a monotherapy to treat vesical calculi is still unfamiliar among many urologists, despite its early introduction in the 1990’s. ESWL monotherapy for vesical calculi was performed in our study in a unique fashion in supine position with full bladder unlike any other previous reported studies. We aimed this study to report our experience with ESWL as a monotherapy in treating urinary bladder stones with a unique technique. A total of 29 patients with vesical calculi were treated with ESWL monotherapy from May 2021 to January 2023 using Dornier delta lithotripter in the supine position with the full bladder without per urethral catheterisation. Patients with stone size > 2.5cm or Hounsfield units > 1200 were excluded. Stone clearance was assessed with the help of fluoroscopy and ultrasonography on a second visit on day 7 after the procedure. Patients were followed up for 3 months. The mean size of vesical calculus was 1.6 cm (SD 0.32), and the mean Hounsfield unit was 940 HU (SD 86.61). None of the study subjects required surgical intervention. The stone clearance was obtained in 93.1% after a single session. The remaining two patients (6.9%) required one more session of ESWL following which stone clearance was obtained. One patient had acute urinary retention, and five (17.2%) patients had mild haematuria. ESWL monotherapy is a safe and effective treatment option for vesical calculi, with minimal or no patient discomfort, when done in supine position without routine per urethral catheterisation as described in the study. It should be considered more often by practicing urologists for vesical calculi.","PeriodicalId":7432,"journal":{"name":"African Journal of Urology","volume":"1 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139460316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although common, most of the cysts are solitary, benign, asymptomatic and seldom clinically significant. But, renal lymphangiectasia is an exception. These are rare lymphatic malformation seen around the kidneys and in the retroperitoneum. It masquerades clinically like ADPKD and renal tumors and radiologically like a complex renal cyst. Although the cyst is benign, it possesses a significant impact on the quality of life. Because of its rarity, the management of this condition has not been well defined in the literature. A clinician must be aware of this rare condition and able to differentiate it from other similar conditions to aid in appropriate management. Hence, we present a case report of a female with bilateral renal lymphangiectasia managed successfully by laparoscopic excision. A 34-year-old hypertensive female came with complaints of bilaterally progressive flank masses for 3 months and breathlessness for 2 weeks. On examination, she had bilateral pitting pedal edema, bilateral palpable renal mass and ascites. She had nephrotic range proteinuria, hypoalbuminemia and normal renal function. Imaging showed 22-cm bilateral peri-renal and hilar multi-loculated cystic lesions, suggestive of bilateral renal lymphangiectasia. Antihypertensives and percutaneous interventions were not successful in relieving her symptoms. Subsequently, she was managed with laparoscopic excision on both sides. After surgery, she had an uneventful postoperative period and good symptomatic relief. No recurrence of the lesion found in follow-up CT imaging after 18 months. Renal lymphangiectasia is a rare yet clinically significant cystic lesion of the kidney. It can be diagnosed confidently by noninvasive imaging modalities. Medical treatment offered for mild symptomatic disease. Patients with severe symptoms need surgical intervention especially if it is not responding to medical management. Minimal invasive approach is feasible and successful in the management of this voluminous disease.","PeriodicalId":7432,"journal":{"name":"African Journal of Urology","volume":"22 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139083587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We retrospectively examined 151 patients with bladder tumors of any type from 2009 to 2021 who underwent V-LABT (visual laser ablation of bladder tumor) with both single- and dual-wavelength diode lasers at Shalamar Hospital Lahore, Pakistan. All procedures were performed by the same surgeon. Shalamar Medical and Dental College review board approved this retrospective cohort study (IRB No. -623-2023). The collected clinical data were consolidated into a single group, encompassing various variables such as the patients’ age, tumor size, number of tumors, tumor location, tumor grade, ablation duration, postoperative catheterization time, bladder discomfort, obturator nerve reflex, intraoperative and postoperative complications, and recurrence of tumors at the ablation sites. The patients were monitored for a minimum of 12 months to observe recurrence at the ablation sites through cystoscopy performed postoperatively every three months. The data were analyzed using Chi-square test, and p value < 0.05 was considered significant. The average age of the 151 patients was found to be 64.72 ± 13.85 years. The size of the tumors was 4.88 ± 2.16 cm, with 48/151 (31.7%) patients having tumors larger than 3 cm. Among the cases studied, 117/151 (77.4%) patients had a single tumor, while the remaining patients had multiple tumors ranging in size from 5 to 7 cm in aggregate. Ablation took 1.57 ± 0.73 h to complete on average. None of the patients required a conversion to TURBT in 151 patients. No obturator reflexes or bladder perforations were observed in any case. Postoperatively, histopathology results showed 53/151 (35%) and 92/151 (60.9%) high- and low-grade tumors. The average catheterization duration was 6.58 ± 1.47 days. Tumors located on difficult sites, such as the anterior wall, lateral wall, and bladder neck, were ablated with ease. There was no recurrence seen on previously tumor ablated sites till 12-month follow-up. Ablation of bladder tumors of any type using single- or dual-wavelength diode laser (980 nm and 980/1470 nm) is safe and feasible. These lasers possess the capability to effectively ablate/coagulate bladder tumors in challenging anatomical locations including diverticular tumors with minimal difficulty.","PeriodicalId":7432,"journal":{"name":"African Journal of Urology","volume":"2 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2024-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139083252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Open transvesical or retropubic prostatectomy remains, in less technologically developed countries, the standard option for treatment of complicated large benign prostatic hyperplasia. Complications rate with open prostatectomy procedures, especially post-operative bleeding and urinary incontinence, represent a real challenge facing urologists. Hopefully, recent advances in endourology section helped greatly in management of complicated benign prostatic hyperplasia and also offered a tool to deal with possible open prostatectomy complications. In a prospective study, fifty (50) male patients with complicated large benign prostatic enlargement associated with large single or multiple bladder stones with stone burden ≥ 3cm3 planned to undergo transvesical prostatectomy divided randomly into two groups. Group (A) included 25 patients who underwent standard T.V.P. and group (B) included 25 patients in whom diagnostic urethro-cystoscopy and a mono-polar resectoscope were used pre- and post-prostatic adenoma enucleation.

Twenty-nine patients were randomized to the P-MSV, while 31 were randomized to S-MSV. The number of ligated veins was counted intraoperative and compared. Follow-up was done at 1 and 3 months including clinical examination, scrotal duplex ultrasound scan, and semen analysis.
