INTRODUCTION
Colovesical fistulas (CVFs) account for approximately 95% enterovesical fistulas (EVFs). About 2/3 CVF cases are diverticular in origin. It mainly presents with urological signs such as pneumaturia and fecaluria. Diagnostic investigations aim at confirming the presence of a fistula. Although conservative management can be chosen for selected individuals, most patients are mainly treated through surgical interventions. CVF represents a challenging condition, which records high rates of morbidity and mortality. Our systematic review aimed at achieving deeper knowledge of both indications, in addition to short- and long-term outcomes related to CVF management.
EVIDENCE ACQUISITION
We performed a systematic literature review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) guidelines. Pubmed/MEDLINE, Embase, Scopus, Cochrane Library and Web of Science databases were used to search all related literature.
EVIDENCE SYNTHESIS
The 22 included articles covered an approximately 37 years-study period (1982-2019), with a total 1365 patient population. CVF etiology was colonic diverticulitis in most cases (87.9%). Pneumaturia (50.1%), fecaluria (40.9%) and urinary tract infections (46.6%) were the most common symptoms. Abdomen computed tomography (CT) scan (80.5%), colonoscopy (74.5%) and cystoscopy (55.9%) were the most frequently performed diagnostic methods. Most CVF patients underwent surgery (97.1%) with open approach (63.3%). Almost all patients had colorectal resection with primary anastomosis with or without ostomy and 53.2% patients underwent primary repair or partial/total cystectomy. Four percent anastomotic leak, 1.8% bladder leak and 3.1% reoperations rates were identified. In an average 5-68-month follow-up, overall morbidity, overall mortality and recurrences rates recorded were 8-49%, 0-63% and 1.2%, respectively.
CONCLUSIONS
CVF mainly affects males and has diverticular origin in almost all cases. Pneumaturia, fecaluria and urinary tract infections are the most characteristic symptoms. Endoscopic tests and imaging are critical tools for diagnostic completion. Management of CVFs depends on the underlying disease. Surgical treatment represents the final approach and consists of resection and reanastomosis of offending intestinal segment, with or without bladder closure. In many cases, a single-stage surgical strategy is selected. Perioperative and long-term outcomes prove good.

INTRODUCTION
In developing countries, Vesico-vaginal fistula (VVF) results following obstetric trauma or iatrogenic during hysterectomy. Large calculus associated with VVF is relatively rare, with the risk factor are presence of foreign body, urinary tract infection, and prolonged duration of disease. Most bladder stones can be found among patients who are bedridden, indwelling urethral catheter, bladder outlet obstruction, infection, and other similar characteristic. We report a case of VVF with bladder and vaginal stone in 37 years old woman and reviews the evaluation and treatment and highlights the role of the healthcare team in managing patients with this condition.
PRESENTATION OF CASE
A 37-year-old, P2A0, woman with a history of hysterectomy three years ago. Intermittent small amounts of watery vaginal discharge developed 1,5 years after the operation. A physical examination revealed mild tenderness over the suprapubic area and no evidence of uterine prolapse. Cystography computed tomography scan with contrast confirmed a fistula vesicovagina with a connection between posterosuperior wall of vesica urinaria and anterosuperior wall of vagina with vesicolithiasis, size 15 × 26 × 14 mm and two vaginal stone with size of 7 × 12 × 17 mm and 4 × 4 × 5 mm. Cystoscopy revealed a grayish stone identified in supratrigone with size of 30 × 12 mm.
DISCUSSION
A hanging intravesical stone on the dome of urinary bladder is scarce, possibly caused by any synthetic and non-absorbable suture material inside of the bladder were encrusted forming a bladder stone. Important risk factors known, which is specific in developing countries, are poor socioeconomic status, malnourishment, low literacy rate, early marriage and childbearing, and inadequate obstetrical care.
CONCLUSION
Although the incidence of VVF accompanied by hanging vaginal stone and a large bladder stone is scarce, reports of any case regarding this study can be beneficial to other studies. Due to its harmful effect, the usage of non-absorbable sutures material during surgery isn't suggested. Hence, the absorbable suture material usage with careful dissection is suggested for any gynecological or pelvic surgery.

Review
Vesicovaginal fistula (VVF) is an abnormal communication between the bladder and the vagina. Prompt diagnosis and timely repair are essential for successful management of these cases. As the clinical scenario is variable, it is difficult to frame uniform guidelines for the management of VVF. Hence, the management protocol is dependent on the treating surgeon and the available resources. Conservative methods should be used in carefully selected patients. Delayed repair is better than the early repair of VVF. Transvaginal route for repair is preferred as it has low morbidity, higher success rates, and minimal complications. Anticholinergics should be used in the postoperative period for better chance of bladder healing. When facilities are available, all the patients may be referred to a tertiary care center where expertise and advanced resources are available. Trained surgeons adapting the new trends should refine the art of VVF repair.

Placenta percreta is the most severe form of placenta accreta and is characterized by placental invasion through the entirety of the myometrium and possibly into extrauterine tissues. It is associated with prior cesarean deliveries and placenta previa. Herein, we present the case of a patient who developed placenta percreta and experienced massive blood loss of 27 liters. She developed many complications over the next 11 months, including deep vein thrombosis, pulmonary embolism, preeclampsia after pregnancy, hematoma, blood clots in the bladder, lactation failure, ileus, vesicovaginal fistula, excessive scar tissue requiring surgery, loss of an ovary, and recurrent bladder perforation. We analyze the mechanisms of these complications and the most common complications associated with placenta percreta.

Review
Interventional radiology of the male urogenital system includes percutaneous and endovascular procedures, and these last consist mostly of transcatheter arterial embolizations. At the kidney level, arterial embolizations are performed mainly for palliative treatment of parenchymal tumors, for renal traumas and, less frequently, for arteriovenous fistulas and renal aneurysms and pseudoaneurysms. These latter may often require emergency intervention as they can cause renal or peri-renal hematomas or significant hematuria. Transcatheter arterial embolization is also an effective therapy for intractable severe bladder hematuria secondary to a number of neoplastic and inflammatory conditions in the pelvis, including unresectable bladder cancer and radiation-induced or cyclophosphamide-induced hemorrhagic cystitis. Endovascular interventional procedures for the penis are indicated for the treatment of post-traumatic priapism. In this article, we review the main endovascular radiological interventions of the male urogenital system, describing the technical aspects, results, and complications of each procedure at the various anatomical districts.

This collection of cases describes some unusual urological tumors and complications related to urological tumors and their treatment. Case 1: A case of uretero-arterial fistula in a patient with long-term ureteral stenting for ureteral oncological stricture and a second case associated to retroperitoneal fibrosis were described. Abdominal CT, pyelography, cystoscopy were useful to show the origin of the bleeding. Angiography is useful for confirming the diagnosis and for subsequent positioning of an endovascular prosthesis which represents a safe approach with reduced post-procedural complications. Case 2: A case of patient who suffered from interstitial pneumonitis during a cycle of intravesical BCG instillations for urothelial cancer. The patient was hospitalized for more than two weeks in a COVID ward for a suspected of COVID-19 pneumonia, but he did not show any evidence of SARS-CoV-2 infection during his hospital stay. Case 3: A case of a young man with a functional urinary bladder paraganglioma who was successfully managed with complete removal of the tumor, leaving the urinary bladder intact. Case 4: A case of a 61 year old male suffering from muscle invasive bladder cancer who was admitted for a radical cystectomy and on the eighth postoperative day developed microangiopathic hemolytic anemia and thrombocytopenia, which clinically defines thrombotic microangiopathy.
